2-{[5-(4-chlorophenyl)-4-(4-methylphenyl)-4h-1,2,4-triazol-3-yl]sulfanyl}acetohydrazide CAS 893726-11-9

Description

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.

2-{[5-(4-chlorophenyl)-4-(4-methylphenyl)-4h-1,2,4-triazol-3-yl]sulfanyl}acetohydrazide (CAS 893726-11-9), molecular formula C17H16ClN5OS and molecular weight 373.86 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 2-{[5-(4-chlorophenyl)-4-(4-methylphenyl)-4h-1,2,4-triazol-3-yl]sulfanyl}acetohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 373.86 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).

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