Methylamine hydrochloride

Methylamine hydrochloride (CAS No.: 593-51-1) is a low molecular weight aliphatic amine salt and a widely used research grade building block in chemical biology and medicinal chemistry, primarily categorized as a synthetic intermediate and nitrogen donor reagent rather than a selective bioactive ligand, with relevance to life sciences workflows through its role in preparing diverse small molecules, probe scaffolds, and candidate libraries for target based and phenotypic screening programs; as the protonated salt form of methylamine, it is typically handled to improve stability and dosing consistency in laboratory procedures, and current mechanistic evidence indicates that methylamine exposure in cellular systems can engage oxidative stress associated processes and inflammatory signaling, including reactive oxygen species generation and NF kappa B linked cytokine response pathways in respiratory cell contexts, supporting its use as a tool compound for studying stress response biology and exposure related cellular perturbation, while direct high affinity target engagement profiles and standardized potency endpoints such as IC50 or EC50 are not broadly established for this simple amine scaffold and are generally reported, when available, across broad concentration windows from micromolar to higher exposure ranges depending on assay format, cell type, and endpoint sensitivity; accordingly, in vitro and in vivo research applications are most commonly implemented in exploratory concentration response designs, process chemistry enabled compound generation, and safety pharmacology style mechanistic studies, and the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
