Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of bioactive molecules, particularly in the development of serotonin receptor modulators. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to construct complex indole derivatives. Also utilized in the synthesis of natural products and functional materials due to its halogenated aromatic structure and methoxy substituent that influence reactivity and binding properties.
