Description
Compared with other compounds in its class, the molecular weight of 192.09 g/mol gives 205533-30-8 3,4,5-trifluoro-2-hydroxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
205533-30-8 3,4,5-trifluoro-2-hydroxybenzoic acid (CAS 205533-30-8) is a high-purity analytical reference standard with the molecular formula C7H3F3O3 and a molecular weight of 192.09 g/mol.
205533-30-8 3,4,5-trifluoro-2-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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 205533-30-8 3,4,5-trifluoro-2-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.
