Chemical Structure
Description
2-(4-Fluorophenyl)-1,3-dioxo-2,3-dihydro-1H-isoindole-5-carboxylic acid (C15H8FNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-(4-Fluorophenyl)-1,3-dioxo-2,3-dihydro-1H-isoindole-5-carboxylic acid (CAS 110768-19-9), molecular formula C15H8FNO4 and molecular weight 285.23 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(4-Fluorophenyl)-1,3-dioxo-2,3-dihydro-1H-isoindole-5-carboxylic acid 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.
