Used as an antioxidant and stabilizer in pharmaceutical formulations due to its ability to scavenge free radicals. It is also employed in cosmetic products, such as sunscreens and skin care items, to protect against oxidative degradation, UV damage, and enhance shelf life. Its phenolic structure makes it suitable for use in analytical chemistry as a derivatization agent for detecting certain biomolecules. Additionally, it serves as an intermediate in the synthesis of other bioactive compounds, including drugs targeting inflammatory and neurodegenerative conditions.
