Compared with other compounds in its class, the molecular weight of 184.28 g/mol gives 1-(2,2,6,6-Tetramethyltetrahydro-2H-pyran-4-yl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(2,2,6,6-Tetramethyltetrahydro-2H-pyran-4-yl)ethan-1-one (CAS 1657017-20-3), molecular formula C11H20O2 and molecular weight 184.28 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2,2,6,6-Tetramethyltetrahydro-2H-pyran-4-yl)ethan-1-one (C11H20O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
