Description
CATO supplies 4-((4-(Benzyloxy)-3-methoxybenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 677754-65-3), a certified reference material (molecular formula C23H19FN4O2S, MW 434.49 g/mol) for analytical method development and quality control.
4-((4-(Benzyloxy)-3-methoxybenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (C23H19FN4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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.
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-(Benzyloxy)-3-methoxybenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione 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.
