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.
(4AR,6S,7R,8R,8aS)-2,2-dimethyl-6-(p-tolylthio)hexahydropyrano[3,2-d][1,3]dioxine-7,8-diol (CAS 905716-02-1) is a high-purity analytical reference standard with the molecular formula C16H22O5S and a molecular weight of 326.41 g/mol.
The molecular framework of (4AR,6S,7R,8R,8aS)-2,2-dimethyl-6-(p-tolylthio)hexahydropyrano[3,2-d][1,3]dioxine-7,8-diol (C16H22O5S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
