Description
CATO supplies 6,8-Dihydroxy-9-isobutyl-2,2,4,4-tetramethyl-5-(3-methylbutanoyl)-4,9-dihydro-1H-xanthene-1,3(2H)-dione (CAS 1807646-92-9), a certified reference material (molecular formula C26H34O6, MW 442.54 g/mol) for analytical method development and quality control.
6,8-Dihydroxy-9-isobutyl-2,2,4,4-tetramethyl-5-(3-methylbutanoyl)-4,9-dihydro-1H-xanthene-1,3(2H)-dione (C26H34O6) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
