CATO manufactures 4H-1,2,4-triazol-4-amine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 4H-1,2,4-triazol-4-amine hydrochloride (CAS 25545-88-4), a certified reference material (molecular formula C2H4N4HCl, MW 120.54 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, 4H-1,2,4-triazol-4-amine hydrochloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
