CAS No 57-39-6 , 1-bis(2-methylaziridin-1-yl)phosphoryl-2-methylaziridine

  • Name: 1-bis(2-methylaziridin-1-yl)phosphoryl-2-methylaziridine
  • Synonyms: ENT 50,003; Tris(2-methyl-1-aziridinyl)phosphine oxide; EMT 50,003;1-bis(2-methylaziridin-1-yl)phosphoryl-2-methylaziridine; Metapoxide; 57-39-6; Methyl aphoxide;Methaphoxide; MAPO;
  • CAS Registry Number:
  • Transport: 2810
  • Boiling Point: 90-92 ºC (0.15-0.3 MMHG)
  • Density: 1.27 g/cm3
  • Safety Statements: Poison by ingestion, skin contact, intraperitoneal, and subcutaneous routes. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental carcinogenic data. Animal experiments suggest cholinesterase inhibition, possibly due to metabolic products of this material in the body. When heated to decomposition it emits very toxic fumes of NOx and POx.
