Chemical Structure

2-(2-Chloro-4,6-dimethylphenoxy)acetic acid CAS 426241-28-3 chemical structure

Description

The occurrence of 2-(2-Chloro-4,6-dimethylphenoxy)acetic acid is closely related to a carboxylic acid group, 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.

2-(2-Chloro-4,6-dimethylphenoxy)acetic acid (CAS 426241-28-3), molecular formula C10H11ClO3 and molecular weight 214.65 g/mol, is a CATO reference standard with documented purity and traceability.

2-(2-Chloro-4,6-dimethylphenoxy)acetic acid (C10H11ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-(2-Chloro-4,6-dimethylphenoxy)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
