Description

Bis(1,1,3,3-Tetramethylbutyl)Hydroquinone is a high-purity, sterically hindered phenolic compound primarily valued for its exceptional performance as an antioxidant and polymerization inhibitor. Its molecular structure provides superior stability and effectiveness in preventing oxidative degradation and unwanted polymerization in sensitive systems. This product is essential for manufacturers in the polymer, petrochemical, and specialty chemical industries who require reliable stabilization for monomers, resins, and other high-value intermediates. CAS No. 63123-15-9.

Application

• Polymerization Inhibitor for vinyl monomers such as styrene, acrylates, and butadiene during production, purification, and storage.
• Antioxidant Stabilizer in lubricants, fuels, and petrochemical feedstocks to extend shelf life and prevent gum formation.
• Process Intermediate for the synthesis of more complex hindered phenol antioxidants and light stabilizers.
• Stabilizing Agent in adhesive and coating formulations to prevent premature curing and maintain viscosity.
• Chemical Intermediate in organic synthesis, leveraging its hindered phenolic structure for further functionalization.
