As a certified reference material (CRM), 5-(2,2-Difluoropropoxy)pyrazine-2-carboxylic acid 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.
5-(2,2-Difluoropropoxy)pyrazine-2-carboxylic acid (CAS 1640975-43-4) is a high-purity analytical reference standard with the molecular formula C8H8F2N2O3 and a molecular weight of 218.16 g/mol.
5-(2,2-Difluoropropoxy)pyrazine-2-carboxylic acid (C8H8F2N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
