Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 149.57 g/mol gives 2-Oxa-5-azabicyclo[2.2.1]heptan-3-one hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Oxa-5-azabicyclo[2.2.1]heptan-3-one hydrochloride (CAS 81025-84-5), a certified reference material (molecular formula C5H7NO2HCl, MW 149.57 g/mol) for analytical method development and quality control.
Structurally, 2-Oxa-5-azabicyclo[2.2.1]heptan-3-one hydrochloride (C5H7NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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 149.57 g/mol, it falls into the low-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.
