Specifications | MSDS | Literature and Reviews


5-Bromo-3-fluoropyridine-2-carboxylic acid (CAS number 669066-91-5), also referred to as 5-bromo-3-fluoropicolinic acid, is a dihalogenated picolinic acid. 5-Bromo-3-fluoropyridine-2-carboxylic acid can be used in the synthesis of allosteric adenosine A2A receptors for insomnia treatments.

5-Bromo-3-fluoropyridine-2-carboxylic acid is also utilised to prepare pyridine-triazole derivatives that coordinate to rhenium (Re) for photoluminescent materials. The reaction begins with the synthesis of pyridinehydrazide, followed by the formation of pyridine-oxadiazol using triethyl orthoformate. The resulting pyridine-oxadiazole then reacts with aniline derivatives to yield the pyridine-triazole ligands. The Re-pyridine-triazole complexes exhibit a photoluminescence quantum yield of up to 55%.
