1,3,2-Dioxaborolane, 2-(9,9-dimethyl-9H-fluoren-4-yl)-4,4,5,5-tetramethyl- CAS 1365692-79-0

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, 1,3,2-Dioxaborolane, 2-(9,9-dimethyl-9H-fluoren-4-yl)-4,4,5,5-tetramethyl- is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1,3,2-Dioxaborolane, 2-(9,9-dimethyl-9H-fluoren-4-yl)-4,4,5,5-tetramethyl- (CAS 1365692-79-0) is a high-purity analytical reference standard with the molecular formula C21H25BO2 and a molecular weight of 320.23 g/mol.

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.
