n-Methylpiperazine

N-Methylpiperazine (CAS 109-01-3, EC 203-639-5), also referred to as 1-Methylpiperazine or NMPRZ, is a cyclic diamine with the molecular formula C5H12N2. It carries no assigned E-code and is classified under HS code 29335995 within the amines category.

In pharmaceutical synthesis, N-Methylpiperazine acts as a building block and catalyst, accelerating reaction rates through its dual basic nitrogen sites. In epoxy and polymer systems, it functions as a crosslinker by reacting with electrophilic sites to form covalent network structures. Water treatment formulations also employ it for its antimicrobial action against bacterial biofilms.

N-Methylpiperazine is supplied as a clear liquid in technical and pharmaceutical grades, with material compliant with REACH registration requirements for European supply. Packaging is available in standard drum and IBC formats suited to industrial procurement volumes. Buyers should confirm grade specification against Ph.Eur. or internal quality standards prior to formulation use.
