Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R,3R,4S,5R,6S)-2-(acetoxymethyl)-4-(allyloxy)-6-(ethylthio)tetrahydro-2H-pyran-3,5-diyl diacetate.
(2R,3R,4S,5R,6S)-2-(acetoxymethyl)-4-(allyloxy)-6-(ethylthio)tetrahydro-2H-pyran-3,5-diyl diacetate (CAS 128716-36-9) is a high-purity analytical reference standard with the molecular formula C17H26O8S and a molecular weight of 390.45 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2R,3R,4S,5R,6S)-2-(acetoxymethyl)-4-(allyloxy)-6-(ethylthio)tetrahydro-2H-pyran-3,5-diyl diacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.45 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,6S)-2-(acetoxymethyl)-4-(allyloxy)-6-(ethylthio)tetrahydro-2H-pyran-3,5-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.
