Chemical Structure
Description
Ethyl 6-cyclobutyl-6-oxohexanoate (CAS 898776-18-6) is a high-purity analytical reference standard with the molecular formula C12H20O3 and a molecular weight of 212.29 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl 6-cyclobutyl-6-oxohexanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 212.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
