Chemical Structure
Description
Based on its molecular formula C13H16O4, (2R,3S,4R)-4-(Benzyloxy)-2-(hydroxymethyl)-3,4-dihydro-2H-pyran-3-ol contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
(2R,3S,4R)-4-(Benzyloxy)-2-(hydroxymethyl)-3,4-dihydro-2H-pyran-3-ol (CAS 58871-08-2), molecular formula C13H16O4 and molecular weight 236.26 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
