Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 488.92 g/mol gives (((2R,3S,4R)-2-(((tert-Butyldimethylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3,4-diyl)bis(oxy))bis(tert-butyldimethylsilane) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(((2R,3S,4R)-2-(((tert-Butyldimethylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3,4-diyl)bis(oxy))bis(tert-butyldimethylsilane) (CAS 121702-69-0), molecular formula C24H52O4Si3 and molecular weight 488.92 g/mol, is a CATO reference standard with documented purity and traceability.
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)bis(oxy))bis(tert-butyldimethylsilane) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 488.92 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
