CATO supplies (2S,3R,4R,5R,6S)-2-Methyl-6-(p-tolylthio)tetrahydro-2H-pyran-3,4,5-triol (CAS 628308-75-8), a certified reference material (molecular formula C13H18O4S, MW 270.34 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H18O4S, (2S,3R,4R,5R,6S)-2-Methyl-6-(p-tolylthio)tetrahydro-2H-pyran-3,4,5-triol contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 270.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
