Chemical Structure
Description
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.
(2R,3S,4S,5R,6R)-3,4,5-tris(Benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-yl acetate (CAS 83462-68-4), molecular formula C36H38O7 and molecular weight 582.68 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2R,3S,4S,5R,6R)-3,4,5-tris(Benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-yl acetate (C36H38O7) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 582.68 g/mol, it falls into the moderately-high-molecular-weight range. 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.
