2,3,5,6-Tetrahydrobenzo[1,2-b:5,4-b']difuran (CAS 57052-75-2), molecular formula C10H10O2 and molecular weight 162.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,3,5,6-Tetrahydrobenzo[1,2-b:5,4-b']difuran (C10H10O2) 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.
