Environmental Fate · 3 items

TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 63(SRC), determined from a measured water solubility(2) and a regression-derived equation(3,SRC), indicates that 1-bromo-3-chloropropane will have high mobility in soil(SRC). Volatilization of 1-bromo-3-chloropropane may be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 2.5X10-4 atm-cu m/mole(SRC), determined using a fragment constant estimation method(4). Volatilization from dry soil surfaces(SRC) is expected based on an extrapolated vapor pressure of 6.4 mm Hg(5,SRC). Based on limited data, this compound is expected to be resistant to aerobic biodegradation(SRC); 1-bromo-3-chloropropane, inoculated with effluent from a biological waste treatment plant, reached 3% of the theoretical BOD in 5 days(6).

AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 63(SRC), determined from a measured water solubility(2) and a regression-derived equation(1,SRC), indicates that 1-bromo-3-chloropropane should not adsorb to suspended solids and sediment in water(SRC). 1-Bromo-3-chloropropane should volatilize from water surfaces(1,SRC) given an estimated Henry's Law constant of 2.5X10-4 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). Estimated half-lives for a model river and model lake are 8 hours and 6 days, respectively(1,SRC). According to a classification scheme(5), an estimated BCF value of 27(1,SRC), from a measured log Kow(4), suggests that bioconcentration in aquatic organisms is low(SRC). Based on limited data, this compound is expected to be resistant to aerobic biodegradation(SRC); 1-bromo-3-chloropropane, inoculated with effluent from a biological waste treatment plant, reached 3% of the theoretical BOD in 5 days(6).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-bromo-3-chloropropane, which has an extrapolated vapor pressure of 6.4 mm Hg at 25 °C(2,SRC), will exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-bromo-3-chloropropane 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 about 18 days(3,SRC).

Pharmacology

Mechanism of Action · 1 item

The present study examines how variations in position, number, and type of halogen substituents affect renal and testicular necrosis, renal and testicular DNA damage, and the tissue distribution of the halogenated propanes. Groups of five male MOL:WIST rats were given single ip injections, ranging from 85 to 3000 um/kg of 1,2-dibromo-3-chloropropane (DBCP), 1,2,3-tribromopropane (TBP), 1,3-dichloro-2-bromopropane (DB2CP), or 1-bromo-2,3-dichloropropane (B2,3DCP), 1,3-dibromopropane, 1,2-dibromopropane, 1,2,3-trichloropropane or 1-bromo-3-chloropropane. The most potent in causing organ damage in both kidney and testes were DBCP and TBP. DB2CP was less organ toxic than DBCP or TBP, but induced more organ damage than B2,3DCP and DC2BP. The ability of the halogenated propanes to induce DNA damage in vivo correlated well with their ability to induce organ damage. However, DNA damage occurred at lower doses and after a shorter period of exposure. DNA damage may be an initial event in the development of organ necrosis by halogenated propanes in general. Testicular DNA damage induced by the halogenated propanes in vivo correlated well with the DNA damage observed in isolated testicular cells in vitro, showing that toxicity was due to in situ activation. The findings established a good relationship between in vivo organ necrogenic effects and DNA damage for a series of halogenated propanes. Both the type, the number, and the position of the halogens affected the toxic potential. The most toxic of the halogenated propanes contained three halogens with at least two vicinal bromines.

Applications · 3 items

Description1-Bromo-3-chloropropane is a halogenated alkane compound containing one bromine atom and one chlorine atom in its structure. Due to the high electronegativity of halogens, the molecule of 1-Bromo-3-chloropropane is highly electrophilic and is easily attacked by electrophilic reagents such as nucleophilic reagents, Lewis acid, etc., which undergoes nucleophilic substitution reactions. The compound is relatively stable at room temperature, but is susceptible to elimination reactions at high temperatures or in the presence of strong acids or bases. In addition, prolonged exposure to air should be avoided because 1-Bromo-3-chloropropane molecules contain halogen atoms that are susceptible to reaction by oxygen and moisture in the air to produce products such as alcohols and aldehydes.

Uses1-Bromo-3-chloropropane is used in the preparation active pharmaceutical ingredient intermediate such as gemfibrozil and reproterol. It is also involved in the preparation of cardiovascular diseases and analgesic drugs materials. It is utilized as a phase separation reagent for the isolation of ribonucleic acid (RNA) in high quality. It is considered as a replacement of chloroform in nucleic acid separations.

General Description1-bromo-3-chloropropane appears as a colorless liquid. Insoluble in water and denser than water. May be toxic by inhalation, ingestion or skin absorption. Used to make pharmaceuticals and other chemicals.

Preparation methods

PreparationThe most common method for producing 1-Bromo-3-chloropropane is through the free-radical addition of anhydrous hydrogen bromide to allyl chloride. Alternatively, it can be prepared by reacting ethylene with methylene chlorobromide.
