Description

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

3-((3,4-Dichlorobenzyl)sulfinyl)-4-ethyl-5-((3-(trifluoromethyl)phenoxy)methyl)-4H-1,2,4-triazole (CAS 956961-74-3), molecular formula C19H16Cl2F3N3O2S and molecular weight 478.32 g/mol, is a CATO reference standard with documented purity and traceability.

3-((3,4-Dichlorobenzyl)sulfinyl)-4-ethyl-5-((3-(trifluoromethyl)phenoxy)methyl)-4H-1,2,4-triazole (C19H16Cl2F3N3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 3-((3,4-Dichlorobenzyl)sulfinyl)-4-ethyl-5-((3-(trifluoromethyl)phenoxy)methyl)-4H-1,2,4-triazole 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.
