Description

3-tert-Butyl-5-Methylpyrocatechol is a specialized phenolic compound widely utilized as a highly effective polymerization inhibitor and antioxidant. Its primary value lies in its ability to prevent premature polymerization and oxidative degradation in sensitive monomers and other reactive chemicals during storage, transport, and processing. This makes it an essential additive for manufacturers in the polymer, petrochemical, and specialty chemical industries who require reliable stabilization of their raw materials to ensure product quality and safety.

Application

• Polymerization Inhibitor for vinyl monomers such as styrene, acrylates, and butadiene during production and storage.
• Antioxidant Stabilizer in fuels, lubricants, and petrochemical feedstocks to prevent gum formation and degradation.
• Intermediate in Organic Synthesis for the production of agrochemicals, pharmaceuticals, and advanced materials.
• Stabilizing Additive in adhesives, coatings, and resin formulations to enhance shelf-life and performance stability.
• UV Stabilizer Component in plastics and elastomers to improve resistance to light-induced degradation.

Quality Control

Our 3-tert-Butyl-5-Methylpyrocatechol is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent performance as a stabilizer. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its nature as an easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain maximum efficacy. Keep away from strong oxidizing agents.
