Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. It serves as a building block in organic reactions where a chlorinated aromatic ring with an ether linkage is required. Its cyclopentyloxy group enhances lipophilicity, making it valuable in drug design for improving blood-brain barrier penetration. Also employed in the development of agrochemicals and specialty polymers due to its stability and reactivity in cross-coupling reactions.
