Chemical Structure
Description
The occurrence of (6-Chloro-5-methylpyridin-3-yl)methylamine hydrochloride is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(6-Chloro-5-methylpyridin-3-yl)methylamine hydrochloride (CAS 1257535-53-7) is a high-purity analytical reference standard with the molecular formula C7H9ClN2HCl and a molecular weight of 193.07 g/mol.
Based on its molecular formula C7H9ClN2HCl, (6-Chloro-5-methylpyridin-3-yl)methylamine hydrochloride contains a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 193.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
