Description
CATO supplies 41940-48-1 5-Methylthiophen-2-amine--hydrogen chloride (1/1) DTXSID20490500 (CAS 41940-48-1), a certified reference material (molecular formula C5H7NSHCl, MW 149.64 g/mol) for analytical method development and quality control.
41940-48-1 5-Methylthiophen-2-amine--hydrogen chloride (1/1) DTXSID20490500 (C5H7NSHCl) 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.
