3-(4-(4-Bromophenyl)-5-((3,4-dichlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine CAS 477330-37-3

Description

Compared with other compounds in its class, the molecular weight of 492.22 g/mol gives 3-(4-(4-Bromophenyl)-5-((3,4-dichlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(4-(4-Bromophenyl)-5-((3,4-dichlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 477330-37-3) is a high-purity analytical reference standard with the molecular formula C20H13BrCl2N4S and a molecular weight of 492.22 g/mol.

3-(4-(4-Bromophenyl)-5-((3,4-dichlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (C20H13BrCl2N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 3-(4-(4-Bromophenyl)-5-((3,4-dichlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
