4-Hydroxy-2,6,6-trimethyl-1-cyclohexenecarboxylic acid (CAS 62218-55-7), molecular formula C10H16O3 and molecular weight 184.23 g/mol, is a CATO reference standard with documented purity and traceability.
4-Hydroxy-2,6,6-trimethyl-1-cyclohexenecarboxylic acid (C10H16O3) 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.
