Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies tert-Butyl 3-(3-bromo-2,2-difluoropropanoyl)pyrrolidine-1-carboxylate (CAS 2766367-06-8), a certified reference material (molecular formula C12H18BrF2NO3, MW 342.18 g/mol) for analytical method development and quality control.
tert-Butyl 3-(3-bromo-2,2-difluoropropanoyl)pyrrolidine-1-carboxylate (C12H18BrF2NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), tert-Butyl 3-(3-bromo-2,2-difluoropropanoyl)pyrrolidine-1-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
