Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinamide-based drugs targeting metabolic and neurological disorders. It serves in the preparation of bioactive molecules due to its structural similarity to vitamin B3 derivatives, enabling modulation of enzyme activity in cellular processes. Commonly employed in research settings for designing compounds with potential antidiabetic, anti-inflammatory, or neuroprotective properties. Its chloro and methyl functional groups allow for selective chemical modifications, making it valuable in medicinal chemistry for structure-activity relationship studies.
