Methylamine Hydrochloride CAS 593-51-1

Description

The occurrence of Methylamine Hydrochloride is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methylamine Hydrochloride (CAS 593-51-1) is a high-purity analytical reference standard with the molecular formula HClCH5N and a molecular weight of 67.52 g/mol.

The molecular framework of Methylamine Hydrochloride (HClCH5N) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
