1,1'-Fumaroyl-bis-aziridin, also known as Fumaryl bis-aziridin or FBA, is a chemical compound with the molecular formula C8H12N2O2. It is a bis-aziridine derivative, which means it contains two aziridine rings connected by a fumaroyl group (a dicarboxylic acid anhydride derived from fumaric acid). FBA is a colorless, crystalline solid that is soluble in water and various organic solvents. It is primarily used as a chemical reagent in the synthesis of various pharmaceuticals and agrochemicals, as well as in the preparation of other organic compounds. Due to its potential cytotoxic and genotoxic properties, FBA is considered hazardous and requires proper handling and disposal.
