Description
As a certified reference material (CRM), (S)-4-Bromo-5-fluoro-2-((1,1,1-trifluoropropan-2-yl)oxy)benzoic 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.
CATO supplies (S)-4-Bromo-5-fluoro-2-((1,1,1-trifluoropropan-2-yl)oxy)benzoic acid (CAS 2222743-02-2), a certified reference material (molecular formula C10H7BrF4O3, MW 331.06 g/mol) for analytical method development and quality control.
(S)-4-Bromo-5-fluoro-2-((1,1,1-trifluoropropan-2-yl)oxy)benzoic acid (C10H7BrF4O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
