4-Chloro-3-fluoropyridine

Description:
4-Chloro-3-fluoropyridine is a heterocyclic organic compound characterized by a pyridine ring substituted with both a chlorine atom and a fluorine atom. The chlorine is located at the 4-position, while the fluorine is at the 3-position of the pyridine ring. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its physical state at room temperature. It has a distinct aromatic odor and is soluble in organic solvents such as ethanol and ether, but has limited solubility in water. 4-Chloro-3-fluoropyridine is primarily used in the synthesis of pharmaceuticals and agrochemicals, serving as an important intermediate in the production of various biologically active compounds. Its reactivity is influenced by the presence of the electronegative halogen substituents, which can participate in nucleophilic substitution reactions. Safety precautions should be observed when handling this compound, as it may pose health risks if inhaled or ingested, and appropriate personal protective equipment should be used.
