Chemical Structure
Description
1,3-Dihydro-3-oxo-1-isobenzofurancarbonitrile 27613-27-0 3-Cyano-3H-isobenzofuranone 3-Cyanophthalide (CAS 27613-27-0), molecular formula C9H11NO2 and molecular weight 165.19 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Dihydro-3-oxo-1-isobenzofurancarbonitrile 27613-27-0 3-Cyano-3H-isobenzofuranone 3-Cyanophthalide (C9H11NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 1,3-Dihydro-3-oxo-1-isobenzofurancarbonitrile 27613-27-0 3-Cyano-3H-isobenzofuranone 3-Cyanophthalide 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.
