Chemical Structure

2,3-Dichloro-4-(trifluoromethyl)benzoic acid CAS 871254-69-2 chemical structure

Description

The occurrence of 2,3-Dichloro-4-(trifluoromethyl)benzoic acid 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.

2,3-Dichloro-4-(trifluoromethyl)benzoic acid (CAS 871254-69-2), molecular formula C8H3Cl2F3O2 and molecular weight 259.01 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,3-Dichloro-4-(trifluoromethyl)benzoic acid (C8H3Cl2F3O2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
