Description
CATO supplies (S)-4,4-Difluoropyrrolidine-2-carboxylic acid compound with 2,2,2-trifluoroacetic acid (1:1) (CAS 1373255-09-4), a certified reference material (molecular formula C5H7F2NO2C2HF3O2, MW 265.13 g/mol) for analytical method development and quality control.
(S)-4,4-Difluoropyrrolidine-2-carboxylic acid compound with 2,2,2-trifluoroacetic acid (1:1) (C5H7F2NO2C2HF3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
As a certified reference material (CRM), (S)-4,4-Difluoropyrrolidine-2-carboxylic acid compound with 2,2,2-trifluoroacetic acid (1:1) 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.
