Chemical Structure
Description
The occurrence of Tert-butyl (2S,4R)-2-(bromomethyl)-4-methylpyrrolidine-1-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tert-butyl (2S,4R)-2-(bromomethyl)-4-methylpyrrolidine-1-carboxylate (CAS 2227198-67-4), molecular formula C11H20BrNO2 and molecular weight 278.19 g/mol, is a CATO reference standard with documented purity and traceability.
Tert-butyl (2S,4R)-2-(bromomethyl)-4-methylpyrrolidine-1-carboxylate (C11H20BrNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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. 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.
