<unk>  (CHBr3) is a pale yellowish liquid with a sweet odor similar to chloroform, a halomethane or haloform. Its refractive index is 1.595 (20 °C, D). Small amounts are formed naturally by plants in the ocean. It is somewhat soluble in water and readily evaporates into the air. Most of the<unk>  that enters the environment is formed as byproducts when chlorine is added to drinking water to kill bacteria.<unk>  is one of the trihalomethanes closely related with fluoroform, chloroform and iodoform. It is soluble in about 800 parts water and is miscible with alcohol, benzene, chloroform, ether, petroleum ether, acetone, and oils. It's LD50 is 7.2 mmol/kg in mice, or 1.8g/kg.
It can be prepared by the haloform reaction using acetone and sodium hypobromite or by the electrolysis of alcoholic solution of potassium or sodium bromide.
