CATO supplies 6-Fluoro-3-methyl-2-(4-oxazol-2-yl-2,3-dihydro-indol-1-yl)-quinoline-4-carboxylic acid (CAS 1229821-40-2), a certified reference material (molecular formula C22H16FN3O3, MW 389.38 g/mol) for analytical method development and quality control.
6-Fluoro-3-methyl-2-(4-oxazol-2-yl-2,3-dihydro-indol-1-yl)-quinoline-4-carboxylic acid (C22H16FN3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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), 6-Fluoro-3-methyl-2-(4-oxazol-2-yl-2,3-dihydro-indol-1-yl)-quinoline-4-carboxylic 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.
