1-(4,5-Dichloro-2-methylphenyl)ethanone CAS 53803-91-1

Description

The occurrence of 1-(4,5-Dichloro-2-methylphenyl)ethanone is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4,5-Dichloro-2-methylphenyl)ethanone (CAS 53803-91-1), molecular formula C9H8Cl2O and molecular weight 203.07 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(4,5-Dichloro-2-methylphenyl)ethanone (C9H8Cl2O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 1-(4,5-Dichloro-2-methylphenyl)ethanone 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.
