5-Methyl-2-phenyl-4-(phenylhydrazinylidene)pyrazol-3-one CAS 53847-70-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methyl-2-phenyl-4-(phenylhydrazinylidene)pyrazol-3-one.

CATO supplies 5-Methyl-2-phenyl-4-(phenylhydrazinylidene)pyrazol-3-one (CAS 53847-70-4), a certified reference material (molecular formula C16H14N4O, MW 278.31 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, 5-Methyl-2-phenyl-4-(phenylhydrazinylidene)pyrazol-3-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 278.31 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-Methyl-2-phenyl-4-(phenylhydrazinylidene)pyrazol-3-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.
