Chemical Structure

2-(4-Methylphenyl)propionyl chloride CAS 51631-67-5 chemical structure

Description

The occurrence of 2-(4-Methylphenyl)propionyl chloride 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.

CATO supplies 2-(4-Methylphenyl)propionyl chloride (CAS 51631-67-5), a certified reference material (molecular formula C10H11ClO, MW 182.65 g/mol) for analytical method development and quality control.

The molecular framework of 2-(4-Methylphenyl)propionyl chloride (C10H11ClO) 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 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.

CATO manufactures 2-(4-Methylphenyl)propionyl chloride 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.
