Dispiro[9H-xanthene-9,1'-[1H,5H]benzo[1,2-c:4,5-c']difuran-5',9''-[9H]xanthene]-3',7'-dione, 3,3'',6,6''-tetrahydroxy- CAS 6936-78-3

Description

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.

Dispiro[9H-xanthene-9,1'-[1H,5H]benzo[1,2-c:4,5-c']difuran-5',9''-[9H]xanthene]-3',7'-dione, 3,3'',6,6''-tetrahydroxy- (CAS 6936-78-3), molecular formula C34H18O10 and molecular weight 586.50 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C34H18O10, Dispiro[9H-xanthene-9,1'-[1H,5H]benzo[1,2-c:4,5-c']difuran-5',9''-[9H]xanthene]-3',7'-dione, 3,3'',6,6''-tetrahydroxy- contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 586.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
