출처

Has apparently not been reported to occur in nature

용도

6-Methylcoumarin is a synthetic fragrance in cosmetics, toiletries and soaps. It mainly used to prepare flavors such as coconut, vanilla and caramel.

일반 설명

6-methylcoumarin appears as white crystals with a flavor of vanilla. Insoluble in water. (NTP, 1992)

제조 및 합성 방법

제조 방법

6-methylcoumarin is synthesized from p-cresol and fumaric acid. Preheat 72% sulfuric acid to 80 °C, add a mixture of fumaric acid and p-cresol, keep the reaction at 160-170 °C for 3-4 hours, cool, pour into crushed ice to precipitate a precipitate, and filter. The filtrate was extracted with benzene, and after adding benzene, the obtained crude product was subjected to vacuum distillation to obtain 6-methylcoumarin. synthesis of 6-methylcoumarin: By heating 6-methyl coumarin-3-carboxylic acid to 300 to 340°C; by condensation of p-cresol-disulfonic acid with fumaric acid in the presence of H2SO4; by condensation of p-homosalicyclic aldehyde with malonic acid in the presence of aniline, followed by heating for the lactone; from salicylaldehyde with propionic acid anhydride and sodium propionate.

When patch tested, the antigen should be applied to the skin for no longer than 30 minutes before UVA exposure because it rapidly becomes inactive. [Marks, p. 224] Safe to use as a flavoring agent in food

Special ReportsBIBRA working groupTA:Toxicity profile. BIBRA Toxicology International:5 (1995).
Reactivity ProfileEsters, such as 6-METHYLCOUMARIN, react with acids to liberate heat along with alcohols and acids. Generates heat with strong oxidizing acids. The reaction may be sufficiently exothermic to ignite the reaction products. Also generates heat with basic solutions. Generates flammable hydrogen with alkali metals and hydrides. Emits acrid smoke and irritating fumes when heated to decomposition.

소화Fires involving this material should be controlled using a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
응급 처치EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.INHALATION: IMMEDIATELY leave the contaminated areatake deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be usedif not available, use a level of protection greater than or equal to that advised under Protective Clothing.INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
비화재 누출 대응SMALL SPILLS AND LEAKAGE: Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.STORAGE PRECAUTIONS: You should store this material in a refrigerator. (NTP, 1992)
처리 방법SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Personal Protective Equipment (PPE)RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Human Toxicity Excerpts/HUMAN EXPOSURE STUDIES/ A Maximization test was carried out on 25 human volunteers. The material was tested at a concn of 4% in petrolatum and produced no sensitization reactions./HUMAN EXPOSURE STUDIES/ 6-Methylcoumarin, a fragrance material, is a photocontact allergen./HUMAN EXPOSURE STUDIES/ The test agent is applied for 24 hr followed by exposure to 3 minimal erythema doses (med) of solar simulated radiation twice weekly for 3 wk (6 exposures) in a panel of 25 white caucasians. The subjects are challenged 2 wk later with long-wave uv radiation. 6-Methylcoumarin gave a high rate of sensitization./SPECIAL STUDIES/ ...Topical pretreatment of /human reconstituted epidermis/ (Episkin), with weak phototoxic compounds /including methyl coumarin/ induced, after UVA exposure, a dose-dependent decr in cell viability, in concordance with an increasing IL-1alpha release. Moreover, compared to chlorpromazine, the lower IL-1alpha release observed with 6-methylcoumarin and ofloxacin could be linked to their weak phototoxic potential. ...
Non-Human Toxicity Excerpts/LABORATORY ANIMALS: Acute Exposure/ 15 exposures of 6-methylcoumarin to the shoulder skin of guinea pigs that had been abraded with a nylon brush rotating @ 13,000 rpm and irradiated with broadband uv irradiation for a 3 wk induction period induced and elicited photoallergic contact dermatitis./LABORATORY ANIMALS: Acute Exposure/ More than 85% of the guinea pigs tested developed photoallergic contact dermatitis. The sensitivity could be detected in 45% of the sensitized animals using 1%, although no reaction was seen with 0.1%./LABORATORY ANIMALS: Acute Exposure/ ...Applied full strength to intact or abraded rabbit skin for 24 hr under occlusion was mildly irritating.../LABORATORY ANIMALS: Acute Exposure/ A male dog fed 150 mg.../kg had to be killed after 39 days because of weakness, emaciation and dehydration, and showed moderate to severe hepatitis and slight to moderate muscle atrophy.For more Non-Human Toxicity Excerpts (Complete) data for METHYL COUMARIN (12 total), please visit the HSDB record page.
Antidote and Emergency TreatmentHuman exposure to second-generation and indandione anticoagulants produces symptoms consistent with anticoagulation effects (e.g., hematomas, hematemesis, hematuria, easy bruisability). Treatment of cases of exposure, particularly of substantial and repeated exposure, may require vitamin K1 therapy and monitoring of prothrombin times for periods of many months.
