Chemical Structure

Methyl 2-(4-chloro-2-fluorophenyl)acetate CAS 917023-04-2 chemical structure

Description

The occurrence of Methyl 2-(4-chloro-2-fluorophenyl)acetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Methyl 2-(4-chloro-2-fluorophenyl)acetate (CAS 917023-04-2), a certified reference material (molecular formula C9H8ClFO2, MW 202.61 g/mol) for analytical method development and quality control.

The molecular framework of Methyl 2-(4-chloro-2-fluorophenyl)acetate (C9H8ClFO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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 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), Methyl 2-(4-chloro-2-fluorophenyl)acetate 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.
