4-Methyl-5-(5-methyl-4-phenylthiophen-3-yl)-4H-1,2,4-triazole-3-thiol CAS 847503-30-4

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-Methyl-5-(5-methyl-4-phenylthiophen-3-yl)-4H-1,2,4-triazole-3-thiol (CAS 847503-30-4), a certified reference material (molecular formula C14H13N3S2, MW 287.40 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4-Methyl-5-(5-methyl-4-phenylthiophen-3-yl)-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 287.40 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), 4-Methyl-5-(5-methyl-4-phenylthiophen-3-yl)-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.
