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,3R,4S,5R,6R)-3,4,5-tris(benzyloxy)-6-methoxytetrahydro-2H-pyran-2-yl)methanol.
((2R,3R,4S,5R,6R)-3,4,5-tris(benzyloxy)-6-methoxytetrahydro-2H-pyran-2-yl)methanol (CAS 4356-80-3) is a high-purity analytical reference standard with the molecular formula C28H32O6 and a molecular weight of 464.55 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, ((2R,3R,4S,5R,6R)-3,4,5-tris(benzyloxy)-6-methoxytetrahydro-2H-pyran-2-yl)methanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 464.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
