Chemical Structure
Description
The molecular framework of (3S,4S,5R,6R)-6-(acetoxymethyl)-4-fluorotetrahydro-2H-pyran-2,3,5-triyl triacetate (C14H19FO9) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 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 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).
(3S,4S,5R,6R)-6-(acetoxymethyl)-4-fluorotetrahydro-2H-pyran-2,3,5-triyl triacetate (CAS 83602-93-1), molecular formula C14H19FO9 and molecular weight 350.29 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
