(1r,3s)-3-(Methoxycarbonyl)-1,2,2-trimethylcyclopentane-1-carboxylic acid (CAS 26252-15-3), molecular formula C11H18O4 and molecular weight 214.26 g/mol, is a CATO reference standard with documented purity and traceability.
(1r,3s)-3-(Methoxycarbonyl)-1,2,2-trimethylcyclopentane-1-carboxylic acid (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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
