(R)-1-((3AR,5R,6S,6aR)-6-(benzyloxy)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-5-yl)-2-(trityloxy)ethan-1-ol (CAS 21090-86-8) is a high-purity analytical reference standard with the molecular formula C36H38O8S and a molecular weight of 630.75 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (R)-1-((3AR,5R,6S,6aR)-6-(benzyloxy)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-5-yl)-2-(trityloxy)ethan-1-ol is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 630.75 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.
