Chemical Structure
Description
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.
(2R,3S,4S,5S,6R)-2-fluoro-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (CAS 2713-54-4), molecular formula C6H11FO5 and molecular weight 182.15 g/mol, is a CATO reference standard with documented purity and traceability.
(2R,3S,4S,5S,6R)-2-fluoro-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (C6H11FO5) contains a carbohydrate-derived structure, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
