3-Benzyl-4-(phenylamino)-1H-1,2,4-triazol-5(4H)-one CAS 75989-69-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Benzyl-4-(phenylamino)-1H-1,2,4-triazol-5(4H)-one.

CATO supplies 3-Benzyl-4-(phenylamino)-1H-1,2,4-triazol-5(4H)-one (CAS 75989-69-4), a certified reference material (molecular formula C15H14N4O, MW 266.30 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-Benzyl-4-(phenylamino)-1H-1,2,4-triazol-5(4H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 266.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), 3-Benzyl-4-(phenylamino)-1H-1,2,4-triazol-5(4H)-one 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.
