Chemical Structure
Description
CATO supplies 2-Methylthiazol-5-amine hydrochloride (CAS 1581780-46-2), a certified reference material (molecular formula C4H6N2SHCl, MW 150.62 g/mol) for analytical method development and quality control.
2-Methylthiazol-5-amine hydrochloride (C4H6N2SHCl) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
