Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2S,3R,4S,5S)-2-(benzyloxy)tetrahydro-2H-pyran-3,4,5-triol (CAS 7473-38-3) is a high-purity analytical reference standard with the molecular formula C12H16O5 and a molecular weight of 240.25 g/mol.
The molecular framework of (2S,3R,4S,5S)-2-(benzyloxy)tetrahydro-2H-pyran-3,4,5-triol (C12H16O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
