(2S,3R)-Ethyl 3-((R)-2,2-dimethyl-1,3-dioxolan-4-yl)-2,3-dihydroxy-2-methylpropanoate (CAS 93635-76-8), molecular formula C11H20O6 and molecular weight 248.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2S,3R)-Ethyl 3-((R)-2,2-dimethyl-1,3-dioxolan-4-yl)-2,3-dihydroxy-2-methylpropanoate (C11H20O6) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
