3, 3-Dimethyl-1, 5-Dioxacycloundecane-6,11-Dione (CAS 94113-47-0), molecular formula C11H18O4 and molecular weight 214.26 g/mol, is a CATO reference standard with documented purity and traceability.
3, 3-Dimethyl-1, 5-Dioxacycloundecane-6,11-Dione (C11H18O4) 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.
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.
