Chemical Structure
Description
N-((2S,3R,4R,5S,6R)-2,4,5-tris(benzyloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide (CAS 55287-54-2) is a high-purity analytical reference standard with the molecular formula C29H33NO6 and a molecular weight of 491.58 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, N-((2S,3R,4R,5S,6R)-2,4,5-tris(benzyloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 491.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
