Chemical Structure

(4-Methylphenyl)phenylethanedione 1-(p-Tolyl)-2-phenylethane-1,2-dione 1-Phenyl-2-p-tolylethane-1,2-dione 2431-00-7 4-Methylbenzil p-Methylbenzil CAS 2431-00-7 chemical structure

Description

The occurrence of (4-Methylphenyl)phenylethanedione 1-(p-Tolyl)-2-phenylethane-1,2-dione 1-Phenyl-2-p-tolylethane-1,2-dione 2431-00-7 4-Methylbenzil p-Methylbenzil is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4-Methylphenyl)phenylethanedione 1-(p-Tolyl)-2-phenylethane-1,2-dione 1-Phenyl-2-p-tolylethane-1,2-dione 2431-00-7 4-Methylbenzil p-Methylbenzil (CAS 2431-00-7) is a high-purity analytical reference standard with the molecular formula C15H12O2 and a molecular weight of 224.25 g/mol.

Structurally, (4-Methylphenyl)phenylethanedione 1-(p-Tolyl)-2-phenylethane-1,2-dione 1-Phenyl-2-p-tolylethane-1,2-dione 2431-00-7 4-Methylbenzil p-Methylbenzil (C15H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 224.25 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.

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.
