3-hydroxy-3H-[1,2,3]triazolo[4,5-b]pyridine 1-oxide CAS CATO-C3D-5795

Description

The occurrence of 3-hydroxy-3H-[1,2,3]triazolo[4,5-b]pyridine 1-oxide is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-hydroxy-3H-[1,2,3]triazolo[4,5-b]pyridine 1-oxide (CAS CATO-C3D-5795), a certified reference material (molecular formula C5H4N4O2, MW 152.11 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-hydroxy-3H-[1,2,3]triazolo[4,5-b]pyridine 1-oxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
