Chemical Structure
Description
The occurrence of (2R,3R,4S,5R,6R)-6-(acetoxymethyl)-5-hydroxy-2-methoxytetrahydro-2H-pyran-3,4-diyl diacetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2R,3R,4S,5R,6R)-6-(acetoxymethyl)-5-hydroxy-2-methoxytetrahydro-2H-pyran-3,4-diyl diacetate (CAS 31873-37-7) is a high-purity analytical reference standard with the molecular formula C13H20O9 and a molecular weight of 320.29 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2R,3R,4S,5R,6R)-6-(acetoxymethyl)-5-hydroxy-2-methoxytetrahydro-2H-pyran-3,4-diyl diacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.29 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.
As a certified reference material (CRM), (2R,3R,4S,5R,6R)-6-(acetoxymethyl)-5-hydroxy-2-methoxytetrahydro-2H-pyran-3,4-diyl diacetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
