Chemical Structure
Description
The occurrence of 8-Fluoro-3-nitroimidazo[1,2-a]pyridine is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
8-Fluoro-3-nitroimidazo[1,2-a]pyridine (CAS 2379918-39-3), molecular formula C7H4FN3O2 and molecular weight 181.12 g/mol, is a CATO reference standard with documented purity and traceability.
8-Fluoro-3-nitroimidazo[1,2-a]pyridine (C7H4FN3O2) 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), 8-Fluoro-3-nitroimidazo[1,2-a]pyridine 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.
