Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
(3R,4S,5R,6R)-3,4,5-tris(benzyloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-2-ol (CAS 47727-93-5), molecular formula C27H30O6 and molecular weight 450.52 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (3R,4S,5R,6R)-3,4,5-tris(benzyloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-2-ol (C27H30O6) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 450.52 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).
