Chemical Structure
Description
As a certified reference material (CRM), Tert-butyl (R)-2-(2,5-difluorophenyl)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.
CATO supplies Tert-butyl (R)-2-(2,5-difluorophenyl)pyrrolidine-1-carboxylate (CAS 1218935-58-0), a certified reference material (molecular formula C15H19F2NO2, MW 283.31 g/mol) for analytical method development and quality control.
Structurally, Tert-butyl (R)-2-(2,5-difluorophenyl)pyrrolidine-1-carboxylate (C15H19F2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 283.31 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
