Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of anti-inflammatory and analgesic drugs. It serves as a building block for active pharmaceutical ingredients due to its phenolic and carboxylic functional groups, which allow for easy modification and derivatization. Also employed in the development of antioxidants and UV stabilizers in specialty polymers, leveraging its phenolic structure to enhance thermal and oxidative stability. Its structural similarity to natural phenolic acids makes it suitable for research in metabolic pathways and drug metabolism studies.
