Chemical Structure

(2R,3R,4S,5R,6R)-4,5-bis(benzyloxy)-2-((benzyloxy)methyl)-6-methoxytetrahydro-2H-pyran-3-ol CAS 19488-49-4 chemical structure

Description

The occurrence of (2R,3R,4S,5R,6R)-4,5-bis(benzyloxy)-2-((benzyloxy)methyl)-6-methoxytetrahydro-2H-pyran-3-ol is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2R,3R,4S,5R,6R)-4,5-bis(benzyloxy)-2-((benzyloxy)methyl)-6-methoxytetrahydro-2H-pyran-3-ol (CAS 19488-49-4) is a high-purity analytical reference standard with the molecular formula C28H32O6 and a molecular weight of 464.55 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, (2R,3R,4S,5R,6R)-4,5-bis(benzyloxy)-2-((benzyloxy)methyl)-6-methoxytetrahydro-2H-pyran-3-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 464.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
