(5-Mercapto-4-phenyl-4H-1,2,4-triazol-3-yl)(phenyl)methanol CAS 21358-25-8

Description

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 supplies (5-Mercapto-4-phenyl-4H-1,2,4-triazol-3-yl)(phenyl)methanol (CAS 21358-25-8), a certified reference material (molecular formula C15H13N3OS, MW 283.35 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, (5-Mercapto-4-phenyl-4H-1,2,4-triazol-3-yl)(phenyl)methanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.35 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).

As a certified reference material (CRM), (5-Mercapto-4-phenyl-4H-1,2,4-triazol-3-yl)(phenyl)methanol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
