Chemical Structure
Description
5-(3-Oxo-1,3-dihydroisobenzofuran-5-yl)furan-2-carbaldehyde (CAS 591212-74-7), molecular formula C13H8O4 and molecular weight 228.20 g/mol, is a CATO reference standard with documented purity and traceability.
5-(3-Oxo-1,3-dihydroisobenzofuran-5-yl)furan-2-carbaldehyde (C13H8O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 5-(3-Oxo-1,3-dihydroisobenzofuran-5-yl)furan-2-carbaldehyde 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.
