Used as an antioxidant in plastics, rubber, and fuels to prevent degradation from oxygen and heat. Acts as a stabilizer in polymer systems, extending material lifespan. Employed in industrial lubricants to inhibit oxidation and maintain performance under high temperatures. Also serves as an intermediate in the synthesis of other specialty chemicals, including UV stabilizers and resin additives. Found in some antimicrobial formulations due to its biocidal properties. However, it should be used with caution due to potential environmental toxicity, particularly to aquatic organisms.
