4-Benzoyl-1-phenyl-3-(prop-1-en-1-yl)-1H-pyrazol-5(4H)-one CAS 88075-58-5

Description

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

4-Benzoyl-1-phenyl-3-(prop-1-en-1-yl)-1H-pyrazol-5(4H)-one (CAS 88075-58-5) is a high-purity analytical reference standard with the molecular formula C19H16N2O2 and a molecular weight of 304.34 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-Benzoyl-1-phenyl-3-(prop-1-en-1-yl)-1H-pyrazol-5(4H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-Benzoyl-1-phenyl-3-(prop-1-en-1-yl)-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.
