3,5-Bis(4-(tert-butyl)phenyl)-4-phenyl-4H-1,2,4-triazole CAS 203799-76-2

Description

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

3,5-Bis(4-(tert-butyl)phenyl)-4-phenyl-4H-1,2,4-triazole (CAS 203799-76-2), molecular formula C28H31N3 and molecular weight 409.57 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3,5-Bis(4-(tert-butyl)phenyl)-4-phenyl-4H-1,2,4-triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 409.57 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 3,5-Bis(4-(tert-butyl)phenyl)-4-phenyl-4H-1,2,4-triazole 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.
