Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
(2R,3R,4S,5S,6R)-2-(acetoxymethyl)-6-(ethylthio)tetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 79389-52-9) is a high-purity analytical reference standard with the molecular formula C16H24O9S and a molecular weight of 392.42 g/mol.
(2R,3R,4S,5S,6R)-2-(acetoxymethyl)-6-(ethylthio)tetrahydro-2H-pyran-3,4,5-triyl triacetate (C16H24O9S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
