(2R,3S,4R)-2-(((tert-Butyldimethylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate CAS 117136-33-1 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (2R,3S,4R)-2-(((tert-Butyldimethylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 378.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

(2R,3S,4R)-2-(((tert-Butyldimethylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate (CAS 117136-33-1), molecular formula C16H30O8Si and molecular weight 378.49 g/mol, is a CATO reference standard with documented purity and traceability.

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.
