Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
(2S,3R,4S,5S)-5-((R)-1,2-diacetoxyethyl)tetrahydrofuran-2,3,4-triyl triacetate (CAS 5531-53-3) is a high-purity analytical reference standard with the molecular formula C16H22O11 and a molecular weight of 390.34 g/mol.
(2S,3R,4S,5S)-5-((R)-1,2-diacetoxyethyl)tetrahydrofuran-2,3,4-triyl triacetate (C16H22O11) contains 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.
