Chemical Structure
Description
CATO supplies (2R,4S)-1-tert-Butyl 2-methyl 4-bromopyrrolidine-1,2-dicarboxylate (CAS 147266-93-1), a certified reference material (molecular formula C11H18BrNO4, MW 308.17 g/mol) for analytical method development and quality control.
(2R,4S)-1-tert-Butyl 2-methyl 4-bromopyrrolidine-1,2-dicarboxylate (C11H18BrNO4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (2R,4S)-1-tert-Butyl 2-methyl 4-bromopyrrolidine-1,2-dicarboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
