Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the production of active pharmaceutical ingredients (APIs) due to its reactive chlorine atoms, which allow for easy functionalization. Commonly employed in the preparation of antitumor, antiviral, and anti-inflammatory agents. Also utilized in agrochemicals for the development of herbicides and pesticides. Its structure is favorable for modifying biological activity in drug design, making it valuable in medicinal chemistry research.
