2,3-Dichloro-6-methoxybenzoic acid CAS 55776-06-2

Description

The occurrence of 2,3-Dichloro-6-methoxybenzoic 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.

2,3-Dichloro-6-methoxybenzoic acid (CAS 55776-06-2), molecular formula C8H6Cl2O3 and molecular weight 221.04 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,3-Dichloro-6-methoxybenzoic acid (C8H6Cl2O3) 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 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), 2,3-Dichloro-6-methoxybenzoic 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.
