4,4A,7,7a-tetrahydro-4,7-ethenocyclobuta[f]isobenzofuran-1,3(3aH,6aH)-dione (CAS 4602-96-4), molecular formula C12H10O3 and molecular weight 202.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,4A,7,7a-tetrahydro-4,7-ethenocyclobuta[f]isobenzofuran-1,3(3aH,6aH)-dione (C12H10O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
