Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 224.30 g/mol gives (2,5-Dimethylphenyl)(m-tolyl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2,5-Dimethylphenyl)(m-tolyl)methanone (CAS 64357-29-5), molecular formula C16H16O and molecular weight 224.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2,5-Dimethylphenyl)(m-tolyl)methanone (C16H16O) is characterized by a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
