4-(4-Bromophenyl)-3-phenyl-4H-1,2,4-triazole CAS 575444-93-8

Description

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

4-(4-Bromophenyl)-3-phenyl-4H-1,2,4-triazole (CAS 575444-93-8), molecular formula C14H10BrN3 and molecular weight 300.15 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-(4-Bromophenyl)-3-phenyl-4H-1,2,4-triazole (C14H10BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 300.15 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), 4-(4-Bromophenyl)-3-phenyl-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.
