Chemical Structure
Description
2-(6-Methoxy-3-oxo-2,3-dihydro-1h-inden-1-ylidene)malononitrile (CAS 507484-59-5) is a high-purity analytical reference standard with the molecular formula C13H8N2O2 and a molecular weight of 224.21 g/mol.
2-(6-Methoxy-3-oxo-2,3-dihydro-1h-inden-1-ylidene)malononitrile (C13H8N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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), 2-(6-Methoxy-3-oxo-2,3-dihydro-1h-inden-1-ylidene)malononitrile 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.
