Description

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

4-(4-Chlorophenyl)-5-methyl-2-(4-nitrobenzyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (CAS 860786-63-6), molecular formula C16H13ClN4O3 and molecular weight 344.75 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-(4-Chlorophenyl)-5-methyl-2-(4-nitrobenzyl)-2,4-dihydro-3H-1,2,4-triazol-3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 4-(4-Chlorophenyl)-5-methyl-2-(4-nitrobenzyl)-2,4-dihydro-3H-1,2,4-triazol-3-one 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.
