| Hazard Information | Back Directory | [General Description]
Off-white powder. | [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. | [Air & Water Reactions]

ChEBI: 2,2-Bis(bromomethyl)propane-1,3-diol is a primary alcohol. | [Hazard]
2,2-Bis(bromomethyl)propane-1,3-diol, or as it is known commercially dibromoneopentyl-glycol (DBNPG), is regulated by the US environmental protection agency (EPA) under the toxic substances control act (TSCA). This compound has been defined as carcinogenic and has been shown to be mutagenic in bacteria.[1] | [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. | [References]
