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 2,5-difluoronicotinate (CAS 1956331-66-0), a certified reference material (molecular formula C10H11F2NO2, MW 215.20 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H11F2NO2, tert-Butyl 2,5-difluoronicotinate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), tert-Butyl 2,5-difluoronicotinate 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.
