Description
CATO supplies 2-(2-Oxo-2h-Chromen-7-Yloxy)-PropionicAcid 2-(2-oxo-2H-chromen-7-yloxy)propanoic acid 304889-93-8 A5597 (CAS 304889-93-8), a certified reference material (molecular formula C12H10O5, MW 234.20 g/mol) for analytical method development and quality control.
2-(2-Oxo-2h-Chromen-7-Yloxy)-PropionicAcid 2-(2-oxo-2H-chromen-7-yloxy)propanoic acid 304889-93-8 A5597 (C12H10O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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), 2-(2-Oxo-2h-Chromen-7-Yloxy)-PropionicAcid 2-(2-oxo-2H-chromen-7-yloxy)propanoic acid 304889-93-8 A5597 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.
