3-Methyl-4-(3-phenylpropylidene)-1H-pyrazol-5(4H)-one CAS 834898-58-7

Description

Structurally, 3-Methyl-4-(3-phenylpropylidene)-1H-pyrazol-5(4H)-one (C13H14N2O) 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 214.26 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.

3-Methyl-4-(3-phenylpropylidene)-1H-pyrazol-5(4H)-one (CAS 834898-58-7) is a high-purity analytical reference standard with the molecular formula C13H14N2O and a molecular weight of 214.26 g/mol.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
