Compared with other compounds in its class, the molecular weight of 260.40 g/mol gives (2R,3R,4R)-2-(((tert-butyldimethylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3,4-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2R,3R,4R)-2-(((tert-butyldimethylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3,4-diol (CAS 124751-19-5) is a high-purity analytical reference standard with the molecular formula C12H24O4Si and a molecular weight of 260.40 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (2R,3R,4R)-2-(((tert-butyldimethylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3,4-diol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.40 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.
