5-[2-(4-Chlorophenyl)-1,3-thiazol-4-yl]-4-ethyl-4H-1,2,4-triazole-3-thiol CAS 338760-74-0

Description

The occurrence of 5-[2-(4-Chlorophenyl)-1,3-thiazol-4-yl]-4-ethyl-4H-1,2,4-triazole-3-thiol is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-[2-(4-Chlorophenyl)-1,3-thiazol-4-yl]-4-ethyl-4H-1,2,4-triazole-3-thiol (CAS 338760-74-0), molecular formula C13H11ClN4S2 and molecular weight 322.84 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 5-[2-(4-Chlorophenyl)-1,3-thiazol-4-yl]-4-ethyl-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 322.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 5-[2-(4-Chlorophenyl)-1,3-thiazol-4-yl]-4-ethyl-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.
