Chemical Structure

2,4,6-Trifluoro-3-hydroxybenzoic acid CAS 91659-63-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 192.09 g/mol gives 2,4,6-Trifluoro-3-hydroxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,4,6-Trifluoro-3-hydroxybenzoic acid (CAS 91659-63-1), molecular formula C7H3F3O3 and molecular weight 192.09 g/mol, is a CATO reference standard with documented purity and traceability.

2,4,6-Trifluoro-3-hydroxybenzoic acid (C7H3F3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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), 2,4,6-Trifluoro-3-hydroxybenzoic 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.
