Safety Profile
Moderately toxic by ingestion, intravenous, and intraperitoneal routes. An experimental teratogen. Other experimental reproductive effects. Questionable carcinogen with experimental tumorigenic data by skin contact. Mutation data reported. Less acutely toxic than ppropiolactone. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, alcohol foam, CO2, dry chemical. Potentially explosive reaction with butanol + 2,4 dichlorophenol + sodium hydroxide. When heated to decomposition it emits acrid and irritating fumes.
