Methyl 2-{[5-({[(4-chlorophenyl)sulfonyl]amino}methyl)-4-methyl-4H-1,2,4-triazol-3-yl]sulfanyl}acetate (CAS 338421-53-7), molecular formula C13H15ClN4O4S2 and molecular weight 390.87 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 2-{[5-({[(4-chlorophenyl)sulfonyl]amino}methyl)-4-methyl-4H-1,2,4-triazol-3-yl]sulfanyl}acetate (C13H15ClN4O4S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
