Chemical Structure

(2R,3S,4R)-4-[(tert-Butyldiphenylsilyl)oxy]-2-[[(tert-butyldiphenylsilyl)oxy]methyl]-3,4-dihydro-2H-pyran-3-ol CAS 352525-68-9 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 (2R,3S,4R)-4-[(tert-Butyldiphenylsilyl)oxy]-2-[[(tert-butyldiphenylsilyl)oxy]methyl]-3,4-dihydro-2H-pyran-3-ol.

CATO supplies (2R,3S,4R)-4-[(tert-Butyldiphenylsilyl)oxy]-2-[[(tert-butyldiphenylsilyl)oxy]methyl]-3,4-dihydro-2H-pyran-3-ol (CAS 352525-68-9), a certified reference material (molecular formula C38H46O4Si2, MW 622.94 g/mol) for analytical method development and quality control.

Structurally, (2R,3S,4R)-4-[(tert-Butyldiphenylsilyl)oxy]-2-[[(tert-butyldiphenylsilyl)oxy]methyl]-3,4-dihydro-2H-pyran-3-ol (C38H46O4Si2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 622.94 g/mol, it falls into the high-molecular-weight range. 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.
