Chemical Structure
Description
1-[(2R)-piperidin-2-yl]ethan-1-one hydrochloride (CAS 111556-21-9), molecular formula C7H13NOHCl and molecular weight 163.65 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-[(2R)-piperidin-2-yl]ethan-1-one hydrochloride (C7H13NOHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 163.65 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
