5-Fluoro-2-iodopyridine(CAS: 159870-80-1)

5-Fluoro-2-iodopyridine is a crystalline solid at room temperature. It has a molecular weight of approximately 257.02 g/mol. This compound is poorly soluble in water but soluble in organic solvents like acetonitrile. It is highly reactive due to the presence of the iodine and fluorine substituents, which can participate in various chemical reactions such as nucleophilic substitution and electrophilic aromatic substitution.

5-Fluoro-2-iodopyridine is typically synthesized through a multistep process involving the iodination of 2-fluoropyridine followed by a nucleophilic substitution reaction. The synthesis often requires the use of iodine and a base like potassium carbonate as a catalyst. The reaction is carried out in an aprotic solvent like acetonitrile, yielding the target compound with good selectivity and moderate to high yield.

5-Fluoro-2-iodopyridine is used in various industries, including pharmaceuticals for the synthesis of drug intermediates, polymers for the development of new materials, and sensors for detecting specific chemical compounds. It also has potential applications in semiconductors due to its electronic properties.

Proper handling of 5-Fluoro-2-iodopyridine requires the use of personal protective equipment (PPE) such as gloves, goggles, and lab coats. The compound should be handled in a well-ventilated area or a fume hood to avoid inhalation. Spills should be handled with appropriate absorbent materials and disposed of according to local regulations. Safety data sheets (SDS) should be consulted for detailed handling and emergency procedures.
