3-(4-Chlorophenyl)-5-phenyl-4-(p-tolyl)-4H-1,2,4-triazole CAS 332910-20-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-Chlorophenyl)-5-phenyl-4-(p-tolyl)-4H-1,2,4-triazole.

3-(4-Chlorophenyl)-5-phenyl-4-(p-tolyl)-4H-1,2,4-triazole (CAS 332910-20-0), molecular formula C21H16ClN3 and molecular weight 345.82 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(4-Chlorophenyl)-5-phenyl-4-(p-tolyl)-4H-1,2,4-triazole (C21H16ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 345.82 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 3-(4-Chlorophenyl)-5-phenyl-4-(p-tolyl)-4H-1,2,4-triazole 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.
