Chemical Structure

1-(4-Hydroxy-2,2,6,6-tetramethyltetrahydro-2H-pyran-4-yl)ethan-1-one CAS 1657017-24-7 chemical structure

Description

Structurally, 1-(4-Hydroxy-2,2,6,6-tetramethyltetrahydro-2H-pyran-4-yl)ethan-1-one (C11H20O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 200.27 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1-(4-Hydroxy-2,2,6,6-tetramethyltetrahydro-2H-pyran-4-yl)ethan-1-one (CAS 1657017-24-7), molecular formula C11H20O3 and molecular weight 200.27 g/mol, is a CATO reference standard with documented purity and traceability.

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.
