1-Phenyl-3-sulfanyl-4,5-dihydro-1h-1,2,4-triazol-5-one CAS 27466-62-2

Description

CATO supplies 1-Phenyl-3-sulfanyl-4,5-dihydro-1h-1,2,4-triazol-5-one (CAS 27466-62-2), a certified reference material (molecular formula C8H7N3OS, MW 193.23 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, 1-Phenyl-3-sulfanyl-4,5-dihydro-1h-1,2,4-triazol-5-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 193.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 1-Phenyl-3-sulfanyl-4,5-dihydro-1h-1,2,4-triazol-5-one 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.
