Chemical Structure

2-(1h-1,2,4-Triazol-1-yl)isonicotinic acid hydrochloride CAS 1193388-48-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(1h-1,2,4-Triazol-1-yl)isonicotinic acid hydrochloride.

2-(1h-1,2,4-Triazol-1-yl)isonicotinic acid hydrochloride (CAS 1193388-48-5) is a high-purity analytical reference standard with the molecular formula C8H6N4O2HCl and a molecular weight of 226.62 g/mol.

2-(1h-1,2,4-Triazol-1-yl)isonicotinic acid hydrochloride (C8H6N4O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 2-(1h-1,2,4-Triazol-1-yl)isonicotinic acid 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.
