Chemical Structure
Description
CATO supplies (4-Chlorothiophen-2-yl)methanamine hydrochloride (CAS 1890186-49-8), a certified reference material (molecular formula C5H6ClNSHCl, MW 184.08 g/mol) for analytical method development and quality control.
(4-Chlorothiophen-2-yl)methanamine hydrochloride (C5H6ClNSHCl) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
