5-([1,1'-Biphenyl]-4-yl)-1H-1,2,4-triazol-3(2H)-one CAS 62036-25-3

Description

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

5-([1,1'-Biphenyl]-4-yl)-1H-1,2,4-triazol-3(2H)-one (CAS 62036-25-3) is a high-purity analytical reference standard with the molecular formula C14H11N3O and a molecular weight of 237.26 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-([1,1'-Biphenyl]-4-yl)-1H-1,2,4-triazol-3(2H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 237.26 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.

As a certified reference material (CRM), 5-([1,1'-Biphenyl]-4-yl)-1H-1,2,4-triazol-3(2H)-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.
