2,3-Dichloroisonicotinaldehyde is primarily used as an intermediate in the synthesis of various pharmaceutical compounds. Its structure allows it to be a key building block in the development of active pharmaceutical ingredients (APIs), particularly those targeting neurological and infectious diseases. Additionally, it serves as a precursor in the production of agrochemicals, contributing to the creation of herbicides and pesticides that protect crops from pests and diseases. The compound is also utilized in organic chemistry research for the development of novel heterocyclic compounds, which have potential applications in material science and drug discovery. Its versatility in chemical reactions makes it a valuable component in the synthesis of complex molecules.
