5-(5-Chloro-2-methoxyphenyl)-4-(3-chloro-4-methoxyphenyl)-4h-1,2,4-triazole-3-thiol CAS 721408-56-6

Description

5-(5-Chloro-2-methoxyphenyl)-4-(3-chloro-4-methoxyphenyl)-4h-1,2,4-triazole-3-thiol (CAS 721408-56-6), molecular formula C16H13Cl2N3O2S and molecular weight 382.26 g/mol, is a CATO reference standard with documented purity and traceability.

5-(5-Chloro-2-methoxyphenyl)-4-(3-chloro-4-methoxyphenyl)-4h-1,2,4-triazole-3-thiol (C16H13Cl2N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-(5-Chloro-2-methoxyphenyl)-4-(3-chloro-4-methoxyphenyl)-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.
