Environmental Fate · 3 Einträge

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 75(SRC), determined from a log Kow of 1.88(2) and a regression-derived equation(3), indicates that methyl anthranilate is expected to have high mobility in soil(SRC). However, aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(4,5), suggesting that mobility may be much lower in some soils(SRC). Volatilization of methyl anthranilate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.9X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 2.7X10-2 mm Hg(6), and water solubility, 2,850 mg/L(7). Methyl anthranilate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(6). Utilizing a soil biodegradation screening test, 100% biodegradation in 64 days of analogous 2-aminobenzoic acid(8) indicates that biodegradation of methyl anthranilate may be an important environmental fate process in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 75(SRC), determined from a log Kow of 1.88(2) and a regression-derived equation(3), indicates that methyl anthranilate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(4) based upon an estimated Henry's Law constant of 1.9X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 2.7X10-2 mm Hg(5), and water solubility, 2,850 mg/L(6). Using this Henry's Law constant and an estimation method(4), volatilization half-lives for a model river and model lake are 24 and 180 days, respectively(SRC). According to a classification scheme(7), an estimated BCF of 8(SRC), from its log Kow(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Methyl anthranilate, present at 50 mg/L, exhibited 100% biodegradation in 20 days when incubated in dechlorinated, charcoal-filtered water(8) indicating that biodegradation of methyl anthranilate may be an important environmental fate process in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), methyl anthranilate, which has a vapor pressure of 2.7X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase methyl anthranilate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 11 hrs(SRC), calculated from its rate constant of 3.5X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Methyl anthranilate contains chromophores that absorb at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC).

Toxicity Summary · 1 Eintrag

IDENTIFICATION AND USE: Methyl anthranilate can occur a colorless to pale-yellow liquid, or crystals with bluish fluorescence. It is used as a non-toxic and non-lethal bird repellent. It is used also in flavorings and perfumes. Although methyl anthranilate was not 100% effective in preventing honey bee stinging, it seemed to reduce number of stings below the average human LD50, indicative of a promising tool for preventing honey bee venom toxicity and wasp colonization. HUMAN STUDIES: Maximization tests were carried out on groups of 24 and 26 volunteers. The material was tested at a 10% concentration in petrolatum and produced no sensitization reactions. It produced no irritation after a 48 hr closed-patch test on human subjects and this result was confirmed when the test was repeated. ANIMAL STUDIES: Methyl anthranilate applied full strength to intact or abraded rabbit skin for 24 hr under occlusion was moderately irritating. Groups of 10 male and 10 female weanling rats were maintained for a period of 115 days on diets containing methyl anthranilate at levels of 0, 3,000 and 10,000 ppm. The only observable effects noted at the 10,000 ppm level were increases in the average weights of the liver and kidneys, and slight (minimal) histological changes in the kidneys. There was no increase in the incidence of primary lung tumors in mice over a period of 24 weeks, that received a total dose of methyl anthranilate of 2.25 or 11.2 g/kg bw (repeated ip injections three times a week for a total of 24 injections). Methyl anthranilate was found to be negative when tested for mutagenicity using the Salmonella/ microsome preincubation assay, Methyl anthranilate was tested in as many as 5 Salmonella typhimurium strains (TA1535, TA1537, TA97, TA98, and TA100) in the presence and absence of metabolic activation. ECOTOXICITY STUDIES: No treatment-related mortality of catfish was observed. Handling times of catfish fingerlings captured by herons from tubs treated with methyl anthranilate-based bird repellent increased at application rates of 19.6 kg/ha or greater.

Ecotoxicity Excerpts · 2 Einträge

/AQUATIC SPECIES/ ...The acute toxicity of methyl anthranilate /was tested/ in a static system against the fry of four species of fish. The LC50 at 24 hr for Atlantic salmon (Salmo salar L.) was 32.3 mg/L, with the no observable effect limit at 6 mg/L.

/AQUATIC SPECIES/ ...The methyl anthranilate-based bird repellent, ReJeX-iT TP-40TM (TP-40), /was evaluated/ for 1) its toxicity to channel catfish fingerlings (catfish), Ictalurus punctatus; 2) its effect on great blue heron (heron), Ardea herodias feeding behavior; 3) its efficacy in reducing heron predation on catfish; and 4) its effects on catfish growth. TP-40 effectively maintained MA /methyl anthranilate/ concentrations near the water's surface and below toxic levels for catfish in the water column. Water samples collected from 0.03 and 0.35 m below the surface of catfish rearing tanks (6,664 L) treated at application rates up to the equivalent of 200 kg/ha contained less than 5 ppm active ingredient, which is less than the no observable effect limit for catfish fry. No treatment-related mortality of catfish was observed. Handling times of catfish fingerlings captured by herons from tubs treated with TP-40 initially increased at application rates of 19.6 kg/ha or greater.

Metabolism/Metabolites · 1 Eintrag

Substantial evidence has accumulated showing that many esters readily undergo enzymatic hydrolysis into their component alcohols and acids. In the case of methyl anthranilate, there is direct experimental evidence showing that this ester, while only slowly hydrolyzed by artificial gastric or pancreatic juice, was readily hydrolyzed in rat liver homogenate (50% in 26.6 minutes) and rapidly hydrolyzed in a homogenate of rat small intestine mucosa (50% in 2.5 minutes). Methyl anthranilate has also been shown to be completely hydrolyzed (>99% in two hours) in pig liver homogenate; but was more resistant to hydrolysis in pig jejunum homogenate and completely unhydrolysed by a pancreatin preparation. The hydrolysis products of methyl anthranilate are, of course, methyl alcohol and anthranilic acid. Methyl alcohol is readily metabolized via well-known pathways to carbon dioxide and water. Anthranilic acid is a normal metabolite in man and is excreted in the urine, primarily, as o-aminohippuric acid and to a lesser extent as anthranilic acid glucuronide.

BeschreibungMethyl anthranilate, also known as MA, methyl 2-amino benzoate or carbo methoxy aniline, is an ester of anthranilic acid. Its chemical formula is C8H9NO2.

OccurrenceMethyl anthranilate naturally occurs in the Concord grapes and other Vitis labrusca grapes or hybrids thereof, and in bergamot, black locust, champaca , gardenia, jasmine, lemon, mandarin, neroli, oranges, rue oil, strawberry, tuberose, wisteria, galangal and ylang ylang. It is also a primary component of the essential apple flavor, along with ethyl acetate and ethyl butyrate.It is also secreted by the musk glands of foxes and dogs, and lends a "sickly sweetness" to the smell of rotting flesh.

VerwendenMethyl anthranilate acts as a bird repellent. It is food-grade and can be used to protect corn, sunflowers, rice, fruit, and golf courses. Dimethyl anthranilate (DMA) has a similar effect. It is also used for the flavor of grape Kool Aid. It is used for flavoring of candy, soft drinks (e.g. grape soda), gums, and drugs. Methyl anthranilate both as a component of various natural essential oils and as a synthesised aroma-chemical is used extensively in modern perfumery . It is also used to produce Schiff's Bases with aldehydes, many of which are also used in perfumery. In a perfumery context the most common Schiff's Base is known as aurantiol - produced by combining methyl anthranilate and hydroxyl citronellal.
