Compared with other compounds in its class, the molecular weight of 196.22 g/mol gives (2R,3S,4S,5R,6S)-2-(hydroxymethyl)-6-mercaptotetrahydro-2H-pyran-3,4,5-triol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2R,3S,4S,5R,6S)-2-(hydroxymethyl)-6-mercaptotetrahydro-2H-pyran-3,4,5-triol (CAS 7534-35-2) is a high-purity analytical reference standard with the molecular formula C6H12O5S and a molecular weight of 196.22 g/mol.
The molecular framework of (2R,3S,4S,5R,6S)-2-(hydroxymethyl)-6-mercaptotetrahydro-2H-pyran-3,4,5-triol (C6H12O5S) is characterized by a carbohydrate-derived structure, a sulfone group. 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.
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.
