tert-Butyldimethyl(((4aR,8R,8aR)-2-phenyl-6-(tributylstannyl)-4,4a,8,8a-tetrahydropyrano[3,2-d][1,3]dioxin-8-yl)oxy)silane CAS 130912-41-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyldimethyl(((4aR,8R,8aR)-2-phenyl-6-(tributylstannyl)-4,4a,8,8a-tetrahydropyrano[3,2-d][1,3]dioxin-8-yl)oxy)silane.

tert-Butyldimethyl(((4aR,8R,8aR)-2-phenyl-6-(tributylstannyl)-4,4a,8,8a-tetrahydropyrano[3,2-d][1,3]dioxin-8-yl)oxy)silane (CAS 130912-41-3) is a high-purity analytical reference standard with the molecular formula C31H54O4SiSn and a molecular weight of 637.55 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, tert-Butyldimethyl(((4aR,8R,8aR)-2-phenyl-6-(tributylstannyl)-4,4a,8,8a-tetrahydropyrano[3,2-d][1,3]dioxin-8-yl)oxy)silane is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 637.55 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.

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.
