Chemical Structure

4-Chloro-3-(2-methylphenyl)propiophenone CAS 898789-44-1 chemical structure

Description

The occurrence of 4-Chloro-3-(2-methylphenyl)propiophenone is closely related to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloro-3-(2-methylphenyl)propiophenone (CAS 898789-44-1), molecular formula C16H15ClO and molecular weight 258.74 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 4-Chloro-3-(2-methylphenyl)propiophenone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 4-Chloro-3-(2-methylphenyl)propiophenone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
