Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2'-(2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(propan-2-ol).
2,2'-(2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(propan-2-ol) (CAS 489433-67-2), molecular formula C11H22O4 and molecular weight 218.29 g/mol, is a CATO reference standard with documented purity and traceability.
2,2'-(2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(propan-2-ol) (C11H22O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
