Chemical Structure
Description
Methyl 1-(pyrrolidin-3-yl)piperidine-3-carboxylate (CAS 903094-48-4), molecular formula C11H20N2O2 and molecular weight 212.29 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 1-(pyrrolidin-3-yl)piperidine-3-carboxylate (C11H20N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
