Chemical Structure
Description
Methyl 2-oxa-5-azabicyclo[2.2.1]Heptane-7-carboxylate (CAS 1290557-43-5), molecular formula C7H11NO3 and molecular weight 157.17 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 2-oxa-5-azabicyclo[2.2.1]Heptane-7-carboxylate (C7H11NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
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.
