Description

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

4-(3-Methylbutylidene)-3-phenyl-1H-pyrazol-5(4H)-one (CAS 834898-53-2), molecular formula C14H16N2O and molecular weight 228.29 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-(3-Methylbutylidene)-3-phenyl-1H-pyrazol-5(4H)-one (C14H16N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 228.29 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-(3-Methylbutylidene)-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.
