4-(2-Fluorophenyl)-5-(3,4,5-trimethoxyphenyl)-4h-1,2,4-triazole-3-thiol CAS 728012-89-3

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 4-(2-Fluorophenyl)-5-(3,4,5-trimethoxyphenyl)-4h-1,2,4-triazole-3-thiol (CAS 728012-89-3), a certified reference material (molecular formula C17H16FN3O3S, MW 361.39 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 4-(2-Fluorophenyl)-5-(3,4,5-trimethoxyphenyl)-4h-1,2,4-triazole-3-thiol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 361.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), 4-(2-Fluorophenyl)-5-(3,4,5-trimethoxyphenyl)-4h-1,2,4-triazole-3-thiol 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.
