Chemical Structure

4-((1,2,3,4-Thiatriazol-5-yl)amino)phenol hydrate CAS 256348-45-5 chemical structure

Description

The occurrence of 4-((1,2,3,4-Thiatriazol-5-yl)amino)phenol hydrate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-((1,2,3,4-Thiatriazol-5-yl)amino)phenol hydrate (CAS 256348-45-5), a certified reference material (molecular formula C7H6N4OSH2O, MW 212.23 g/mol) for analytical method development and quality control.

Structurally, 4-((1,2,3,4-Thiatriazol-5-yl)amino)phenol hydrate (C7H6N4OSH2O) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 212.23 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 4-((1,2,3,4-Thiatriazol-5-yl)amino)phenol hydrate 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.
