Chemical Structure
Description
The occurrence of 5-(2-Aminoethyl)-4-methyl-4h-1,2,4-triazole-3-thiol hydrochloride is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(2-Aminoethyl)-4-methyl-4h-1,2,4-triazole-3-thiol hydrochloride (CAS 1258652-03-7), molecular formula C5H10N4SHCl and molecular weight 194.68 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, 5-(2-Aminoethyl)-4-methyl-4h-1,2,4-triazole-3-thiol hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
