As a certified reference material (CRM), 5-[((3Z)-5-Fluoro-2-oxo-1,2-dihydroindol-3-ylidene)methyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid [2-hydroxy-3-(morpholin-4-yl)propyl]amide 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.
5-[((3Z)-5-Fluoro-2-oxo-1,2-dihydroindol-3-ylidene)methyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid [2-hydroxy-3-(morpholin-4-yl)propyl]amide (CAS 452104-85-7), molecular formula C23H27FN4O4 and molecular weight 442.48 g/mol, is a CATO reference standard with documented purity and traceability.
5-[((3Z)-5-Fluoro-2-oxo-1,2-dihydroindol-3-ylidene)methyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid [2-hydroxy-3-(morpholin-4-yl)propyl]amide (C23H27FN4O4) contains a flavonoid 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.
