Used as an intermediate in organic synthesis, particularly in pharmaceutical manufacturing. It serves as a building block for introducing the 4-fluorobenzoate group in active pharmaceutical ingredients. Commonly employed in the development of drugs requiring enhanced metabolic stability and lipophilicity due to the presence of the fluorine atom. Also utilized in the synthesis of agrochemicals and specialty polymers where fluorinated aromatic esters improve material performance. Its tert-butyl ester group allows for selective deprotection under mild acidic conditions, making it valuable in multi-step synthetic routes.
