(2-Chlorophenyl)(2,5-dimethylphenyl)methanone CAS 70132-79-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-Chlorophenyl)(2,5-dimethylphenyl)methanone.

(2-Chlorophenyl)(2,5-dimethylphenyl)methanone (CAS 70132-79-5) is a high-purity analytical reference standard with the molecular formula C15H13ClO and a molecular weight of 244.72 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, (2-Chlorophenyl)(2,5-dimethylphenyl)methanone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
