Chemical Structure
Description
4-(4-(4-Bromophenyl)-5-((2,6-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.
4-(4-(4-Bromophenyl)-5-((2,6-dichlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 477330-42-0), molecular formula C20H13BrCl2N4S and molecular weight 492.22 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(4-(4-Bromophenyl)-5-((2,6-dichlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine 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.
