4-(3,4-Dichlorophenyl)-5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-thiol CAS 438031-65-3

Description

Compared with other compounds in its class, the molecular weight of 352.24 g/mol gives 4-(3,4-Dichlorophenyl)-5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(3,4-Dichlorophenyl)-5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-thiol (CAS 438031-65-3), a certified reference material (molecular formula C15H11Cl2N3OS, MW 352.24 g/mol) for analytical method development and quality control.

The molecular framework of 4-(3,4-Dichlorophenyl)-5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-thiol (C15H11Cl2N3OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
