Chemical Structure

3,6-Di-tert-butyl-9H-fluoren-9-one CAS 58775-15-8 chemical structure

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.

CATO supplies 3,6-Di-tert-butyl-9H-fluoren-9-one (CAS 58775-15-8), a certified reference material (molecular formula C21H24O, MW 292.41 g/mol) for analytical method development and quality control.

3,6-Di-tert-butyl-9H-fluoren-9-one (C21H24O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
