Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. It serves as a building block for nicotinamide derivatives, which are important in the creation of bioactive molecules. Its chloro and amide functional groups allow for selective reactions, enabling the formation of more complex structures. Commonly employed in medicinal chemistry for designing compounds with potential neurological or metabolic activity. Also utilized in research settings for synthesizing analogs in structure-activity relationship (SAR) studies.
