Chemical Structure
Description
4,9-Dimethoxy-5,8-methanonaphtho[2,3-c]furan-1,3(5H,8H)-dione (CAS 650616-59-4) is a high-purity analytical reference standard with the molecular formula C15H12O5 and a molecular weight of 272.25 g/mol.
The molecular framework of 4,9-Dimethoxy-5,8-methanonaphtho[2,3-c]furan-1,3(5H,8H)-dione (C15H12O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
