Chemical Structure
Description
The occurrence of Tert-butyl (S)-2-(bromomethyl)-4,4-dimethoxypyrrolidine-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 (S)-2-(bromomethyl)-4,4-dimethoxypyrrolidine-1-carboxylate (CAS 1657021-04-9) is a high-purity analytical reference standard with the molecular formula C12H22BrNO4 and a molecular weight of 324.21 g/mol.
Tert-butyl (S)-2-(bromomethyl)-4,4-dimethoxypyrrolidine-1-carboxylate (C12H22BrNO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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.
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.
