4,9-Diphenyl-3a,4,9,9a-tetrahydro-4,9-epoxynaphtho[2,3-c]furan-1,3-dione CAS 75925-22-3

Description

The occurrence of 4,9-Diphenyl-3a,4,9,9a-tetrahydro-4,9-epoxynaphtho[2,3-c]furan-1,3-dione is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,9-Diphenyl-3a,4,9,9a-tetrahydro-4,9-epoxynaphtho[2,3-c]furan-1,3-dione (CAS 75925-22-3), molecular formula C24H16O4 and molecular weight 368.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 4,9-Diphenyl-3a,4,9,9a-tetrahydro-4,9-epoxynaphtho[2,3-c]furan-1,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
