Description
Compared with other compounds in its class, the molecular weight of 198.26 g/mol gives Ethyl 4,4-dimethyl-2-oxocyclohexanecarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 4,4-dimethyl-2-oxocyclohexanecarboxylate (CAS 36168-42-0) is a high-purity analytical reference standard with the molecular formula C11H18O3 and a molecular weight of 198.26 g/mol.
Ethyl 4,4-dimethyl-2-oxocyclohexanecarboxylate (C11H18O3) 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.
As a certified reference material (CRM), Ethyl 4,4-dimethyl-2-oxocyclohexanecarboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
