Documented Uses

• Used in organic synthesis and as a flame retardant; [HSDB]
• Addition /to isoprene/ is induced using bromotrichloromethane in a 3:1 mol ratio to isoprene by x-irradiation at 60 Gy/min. The main reaction yields a mixture of ca 75% 1,4 and 25% 4,1 addition product
• At 225-275 °C bromination of the /chloroform/ vapor yields bromochloromethanes: CCl3Br, CCl2Br2, CClBr3
• Methane, bromotrichloro-: ACTIVE
• AFTER ORAL ADMIN OF BROMOTRICHLOROMETHANE TO RATS, FORMATION OF RADICAL CBRCL2 AND CCL3 BY LIVER METABOLISM MAY OCCUR.
• UTILIZING THE SPIN-TRAPPING AGENT PHENYL-TERT-BUTYL NITRONE, A FREE RADICAL, CCL3, WAS DETECTED WHICH IS PRODUCED FROM CARBON TETRACHLORIDE OR BROMOTRICHLOROMETHANE DURING ENZYMIC OXIDATION OF NADPH BY RAT LIVER MICROSOMES.
