Dibromochloromethane

Dibromo-chloro-methane

CHBr2Cl (205.8133)


Dibromochloromethane belongs to the family of Organochlorides. These are organic compounds containing a chlorine atom

   

Bromoform

Methyl tribromide

CHBr3 (249.7628)


Bromoform, also known as Tribromomethane or Methyl tribromide, is classified as a member of the Trihalomethanes. Trihalomethanes are organic compounds in which exactly three of the four hydrogen atoms of methane (CH4) are replaced by halogen atoms. Trace amounts of 1,2-dibromoethane occur naturally in the ocean, where it is formed probably by algae and kelp. Bromoform is formally rated as an unfounded non-carcinogenic (IARC 3) potentially toxic compound. Exposure to bromoform may occur from the consumption of chlorinated drinking water. The acute (short-term) effects from inhalation or ingestion of high levels of bromoform in humans and animals consist of nervous system effects such as the slowing down of brain functions, and injury to the liver and kidney. Chronic (long-term) animal studies indicate effects on the liver, kidney, and central nervous system (CNS) from oral exposure to bromoform. Human data are considered inadequate in providing evidence of cancer by exposure to bromoform, while animal data indicate that long-term oral exposure can cause liver and intestinal tumors. Bromoform has been classified as a Group B2, probable human carcinogen. Most of the bromoform that enters the environment is formed as disinfection byproducts known as the trihalomethanes when chlorine is added to drinking water or swimming pools to kill bacteria. In the past, it was used as a solvent, sedative and flame retardant, but now it is mainly used as a laboratory reagent. Bromine is a halogen element with the symbol Br and atomic number 35. Diatomic bromine does not occur naturally, but bromine salts can be found in crustal rock. Bromoform is a pale yellow liquid at room temperature, with a high refractive index, very high density, and sweet odor is similar to that of chloroform.

Bromodichloromethane

Bromodichloromethane, 14C-labeled

CHBrCl2 (161.8639)


Bromodichloromethane, also known as dichlorobromomethane or monobromodichloromethane, is classified as a member of the trihalomethanes. Trihalomethanes are organic compounds in which exactly three of the four hydrogen atoms of methane (CH4) are replaced by halogen atoms. Bromodichloromethane is a colorless, nonflammable liquid. Small amounts are formed naturally by algae in the oceans. Some of it will dissolve in water, but it readily evaporates into air. Only small quantities of bromodichloromethane are produced in the United States. The small quantities that are produced are used in laboratories or to make other chemicals. However, most bromodichloromethane is formed as a by-product when chlorine is added to drinking water to kill bacteria. Bromodichloromethane has been formerly used as a flame retardant, and a solvent for fats and waxes and because of its high density for mineral separation. Now it is only used as a reagent or intermediate in organic chemistry. Bromodichloromethane can also occur in municipally-treated drinking water as a by-product of the chlorine disinfection process.
