Chemical Structure

2-(2-Chloro-4,5-dimethylphenoxy)acetic acid CAS 1585-23-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 214.65 g/mol gives 2-(2-Chloro-4,5-dimethylphenoxy)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(2-Chloro-4,5-dimethylphenoxy)acetic acid (CAS 1585-23-5), a certified reference material (molecular formula C10H11ClO3, MW 214.65 g/mol) for analytical method development and quality control.

The molecular framework of 2-(2-Chloro-4,5-dimethylphenoxy)acetic acid (C10H11ClO3) is characterized by a carboxylic acid group, 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).

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 2-(2-Chloro-4,5-dimethylphenoxy)acetic acid 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.
