Overview
Methylamine hydrochloride (CAS 593-51-1 ), also sold as monomethylamine hydrochloride, is the stable, solid salt form of methylamine used where the free base gas would be impractical to handle.
It serves as a controlled source of methylamine in synthesis and research, releasing the reactive amine under controlled conditions. In pharmaceutical manufacturing, it functions as a key building block.
This compound is essential in the synthesis of active pharmaceutical ingredients, including antivirals, analgesics, and CNS compounds. Agrochemical producers use it to manufacture herbicides and pesticides.
It is frequently utilized where a methylamine moiety is required in the final structure. In biotechnology and life sciences, it is used in buffer preparation and as a reagent in biochemical assays.
Research laboratories also use it as a reference standard and synthetic intermediate in small-scale organic synthesis. The product is supplied as a white crystalline powder or granular solid.
It is available in technical and pharmaceutical-grade specifications to meet the purity requirements of both industrial synthesis and regulated drug manufacturing. This ensures compliance with USP and BP standards.
Packaging ranges from laboratory-scale quantities to bulk industrial supply. Documentation is available to support GMP procurement workflows and other regulatory requirements for global distribution.
