Compared with other compounds in its class, the molecular weight of 212.63 g/mol gives (2S,3R,4S,5R,6R)-2-(chloromethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2S,3R,4S,5R,6R)-2-(chloromethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol (CAS 58178-94-2) is a high-purity analytical reference standard with the molecular formula C7H13ClO5 and a molecular weight of 212.63 g/mol.
(2S,3R,4S,5R,6R)-2-(chloromethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol (C7H13ClO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
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.
