Description

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

3-Methyl-4-(2-methylbenzoyl)-1-phenyl-1H-pyrazol-5(4H)-one (CAS 73087-94-2) is a high-purity analytical reference standard with the molecular formula C18H16N2O2 and a molecular weight of 292.33 g/mol.

The molecular framework of 3-Methyl-4-(2-methylbenzoyl)-1-phenyl-1H-pyrazol-5(4H)-one (C18H16N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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), 3-Methyl-4-(2-methylbenzoyl)-1-phenyl-1H-pyrazol-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.
