3,5-Di-tert-butyl-4-hydroxyphenylpropionic acid(CAT: R036423) is a sterically hindered phenolic compound known for its potent antioxidant properties. Featuring bulky tert-butyl groups at the 3 and 5 positions and a hydroxyphenylpropionic acid backbone, it is highly effective at scavenging free radicals and preventing oxidative degradation in polymers, plastics, and lubricants. The carboxylic acid group provides reactive functionality for further derivatization or incorporation into antioxidant additives and stabilizers. It is often used as a building block in synthesizing more complex hindered phenol antioxidants.
