4-Benzyl-3-phenyl-1H-pyrazol-5(4H)-one CAS 40115-65-9

Description

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

CATO supplies 4-Benzyl-3-phenyl-1H-pyrazol-5(4H)-one (CAS 40115-65-9), a certified reference material (molecular formula C16H14N2O, MW 250.30 g/mol) for analytical method development and quality control.

Structurally, 4-Benzyl-3-phenyl-1H-pyrazol-5(4H)-one (C16H14N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 250.30 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 4-Benzyl-3-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.
