Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 159.12 g/mol gives Ethyl 2-fluorooxazole-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-fluorooxazole-4-carboxylate (CAS 1167056-73-6), molecular formula C6H6FNO3 and molecular weight 159.12 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-fluorooxazole-4-carboxylate (C6H6FNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Ethyl 2-fluorooxazole-4-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.
