Chemical Structure

(3aR,5R,6aS)-5-(((tert-Butyldiphenylsilyl)oxy)methyl)-2,2-dimethyldihydrofuro[2,3-d][1,3]dioxol-6(3aH)-one CAS 75783-45-8 chemical structure

Description

(3aR,5R,6aS)-5-(((tert-Butyldiphenylsilyl)oxy)methyl)-2,2-dimethyldihydrofuro[2,3-d][1,3]dioxol-6(3aH)-one (CAS 75783-45-8) is a high-purity analytical reference standard with the molecular formula C24H30O5Si and a molecular weight of 426.58 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, (3aR,5R,6aS)-5-(((tert-Butyldiphenylsilyl)oxy)methyl)-2,2-dimethyldihydrofuro[2,3-d][1,3]dioxol-6(3aH)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 426.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
