Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 141.14 g/mol gives 2-Ethoxy-5-fluoropyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Ethoxy-5-fluoropyridine (CAS 858675-61-3), molecular formula C7H8FNO and molecular weight 141.14 g/mol, is a CATO reference standard with documented purity and traceability.
2-Ethoxy-5-fluoropyridine (C7H8FNO) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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), 2-Ethoxy-5-fluoropyridine 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.
