Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides. Its bulky tert-butyl group enhances lipophilicity, making it valuable in modifying the solubility and stability of active ingredients. Also employed in the production of specialty polymers and UV stabilizers due to its resistance to degradation under light exposure. Additionally, it serves as a building block in organic synthesis for introducing aromatic carboxylic acid functionality with steric hindrance.
