CAS 57-39-6 — Tris(2-methyl-1-aziridinyl)phosphine oxide (MAPO)

Tris(2-methyl-1-aziridinyl)phosphine oxide (MAPO) is a highly reactive organophosphorus compound primarily used as a cross-linking agent in resins, adhesives, and coatings to enhance durability and chemical resistance. It is also employed in the production of flame-retardant materials and as a curing agent for epoxy systems. MAPO has a CAS number of 57-39-6, a molecular formula of C9H18N3OP, and a molecular weight of 215.23 g/mol. It is stored at ambient conditions but requires careful handling due to its hazardous nature, indicated by the signal word "Danger." Molekula supplies Tris(2-methyl-1-aziridinyl)phosphine oxide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
