Description

2-((3,5-Di-tert-Butyl-2-Hydroxyphenyl)Amino)Benzoic Acid is a high-purity, sterically hindered phenolic compound that serves as a versatile intermediate and functional additive. Its molecular structure provides excellent antioxidant and metal-chelating properties, making it valuable for enhancing material stability and performance. This product is essential for researchers and manufacturers in the polymer, lubricant, and specialty chemical industries seeking to develop advanced formulations with improved longevity and resistance to oxidative degradation.

Application

• Polymer Stabilizer: Acts as a high-performance antioxidant and light stabilizer in polyolefins (e.g., PP, PE), engineering plastics, and synthetic rubbers to prevent thermal and oxidative degradation during processing and service life.
• Lubricant & Fuel Additive: Used as an antioxidant additive in synthetic lubricants, greases, and industrial fuels to inhibit sludge formation, reduce viscosity increase, and extend operational lifespan.
• Chemical Intermediate: Serves as a key building block for synthesizing more complex hindered amine light stabilizers (HALS), metal deactivators, and other specialty antioxidants.
• Coating & Adhesive Formulations: Incorporated into paints, varnishes, and adhesive systems to protect against yellowing and embrittlement caused by UV exposure and heat.
• Research & Development: Utilized in academic and industrial R&D for studying structure-activity relationships in antioxidant chemistry and developing new stabilization systems.
