4-Fluoropicolinic acid(CAS: 886371-78-4)

4-Fluoropicolinic acid is a white crystalline solid with a molecular weight of approximately 164.02 g/mol. It is slightly soluble in water and has limited solubility in common organic solvents. This compound is known for its reactivity, particularly in nucleophilic substitution reactions and as a Lewis acid catalyst in organic synthesis.

4-Fluoropicolinic acid is usually synthesized by the fluorination of picolinic acid using reagents such as fluorine gas or hydrogen fluoride in the presence of a suitable catalyst, often a transition metal like copper. The reaction is typically conducted under anhydrous conditions and requires careful control of reaction temperature and pressure to achieve high yield and selectivity.

4-Fluoropicolinic acid is utilized in various industries, particularly in the pharmaceutical sector for the synthesis of drugs. It also finds applications in the production of polymers and as a precursor in sensor and semiconductor manufacturing due to its chemical reactivity and Lewis acidic properties.

Proper personal protective equipment (PPE) is essential when handling 4-Fluoropicolinic acid, including gloves, safety goggles, and protective clothing. It should be stored in a cool, dry place away from sources of heat and moisture. Spills should be handled carefully using appropriate absorbents, and the area should be well-ventilated. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
