Methyl 2-oxa-5-azabicyclo[2.2.1]Heptane-4-carboxylate hydrochloride (CAS 2137451-00-2), molecular formula C7H11NO3HCl and molecular weight 193.63 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 2-oxa-5-azabicyclo[2.2.1]Heptane-4-carboxylate hydrochloride (C7H11NO3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
