CATO supplies (S)-(+)-Ketopinic acid Bicyclo[2.2.1]?heptane-?1-?carboxylic acid, 7,?7-?dimethyl-?2-?oxo-?, (+)-Ketopic acid (1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptane-1-carboxylic acid 40724-67-2 (CAS 40724-67-2), a certified reference material (molecular formula C10H14O3, MW 182.22 g/mol) for analytical method development and quality control.
(S)-(+)-Ketopinic acid Bicyclo[2.2.1]?heptane-?1-?carboxylic acid, 7,?7-?dimethyl-?2-?oxo-?, (+)-Ketopic acid (1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptane-1-carboxylic acid 40724-67-2 (C10H14O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
