Chemical Structure
Description
The occurrence of 7-Bromo-4-fluoropyrazolo[1,5-a]pyridine-3-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Bromo-4-fluoropyrazolo[1,5-a]pyridine-3-carboxylic acid (CAS 2396750-30-2), a certified reference material (molecular formula C8H4BrFN2O2, MW 259.03 g/mol) for analytical method development and quality control.
7-Bromo-4-fluoropyrazolo[1,5-a]pyridine-3-carboxylic acid (C8H4BrFN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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. 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), 7-Bromo-4-fluoropyrazolo[1,5-a]pyridine-3-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.
