Methylamine hydrochloride

Methylamine hydrochloride (CAS 593-51-1, EC 209-795-0) is the stable salt form of methylamine, formed by neutralising the gas with hydrochloric acid. It is also referred to as methylammonium chloride, monomethylamine HCl, and methanaminium chloride. No E-code designation applies to this substance.

In pharmaceutical synthesis, it serves as a controlled nitrogen source for constructing secondary amine intermediates, where its fixed ionic form allows precise stoichiometric dosing. In agrochemical manufacturing, it functions as a building block for herbicide and pesticide active ingredients. Its buffering capacity also makes it useful for maintaining stable pH conditions in biological assay media.

Methylamine hydrochloride is supplied as a technical-grade powder and is subject to REACH registration requirements within the EU. Procurement teams should note that the substance falls under precursor monitoring regulations in several jurisdictions. Standard packaging formats include fibre drums and multi-layer bags; documentation including SDS and CoA is available on request.
