(2R,3R,4S,5R,6S)-4,5-Bis(benzyloxy)-2-((benzyloxy)methyl)-6-(phenylthio)tetrahydro-2H-pyran-3-ol (CAS 97974-20-4), molecular formula C33H34O5S and molecular weight 542.69 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2R,3R,4S,5R,6S)-4,5-Bis(benzyloxy)-2-((benzyloxy)methyl)-6-(phenylthio)tetrahydro-2H-pyran-3-ol (C33H34O5S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 542.69 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
