2-Chloro-4-fluorobenzohydrazide is primarily used in organic synthesis as a key intermediate for the preparation of various heterocyclic compounds. Its structure allows it to participate in the formation of hydrazones, which are valuable in the development of pharmaceuticals and agrochemicals. The compound is often utilized in the synthesis of active pharmaceutical ingredients (APIs) due to its ability to introduce both chloro and fluoro substituents into target molecules, enhancing their biological activity. Additionally, it serves as a building block in the creation of dyes, pigments, and other specialty chemicals, where its unique substitution pattern contributes to desired properties such as stability and reactivity.
