The Uses of 2,2-Bis(bromomethyl)propane-1,3-diol

It is a brominated flame retardant, previously shown to be a multisite carcinogen in experimental animals. The compound is used as a fire retardant in unsaturated polyester resins, in molded products, and in rigid polyurethane foam. It shows clear evidence of carcinogenicity and genotoxicity activity.

Definition

ChEBI: 2,2-Bis(bromomethyl)propane-1,3-diol is a primary alcohol.

General Description

Off-white powder.

Air & Water Reactions

Hygroscopic . Insoluble in water.

Reactivity Profile

A brominated alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

Fire Hazard

Literature sources indicate that 2,2-Bis(bromomethyl)propane-1,3-diol is nonflammable.

Carcinogenicity

The flame retardant 2,2-bis(bromomethyl)-1,3-propanediol, technical grade, is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
