Chemical Structure
Description
The occurrence of 1-(Piperidine-4-carbonyl)piperidin-4-one hydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(Piperidine-4-carbonyl)piperidin-4-one hydrochloride (CAS 1189684-40-9), molecular formula C11H18N2O2HCl and molecular weight 246.73 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H18N2O2HCl, 1-(Piperidine-4-carbonyl)piperidin-4-one hydrochloride contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 246.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
