Description

4,6-Di-tert-Butyl-3-Methoxycatechol is a specialized phenolic antioxidant and polymerization inhibitor. This compound matters for its ability to effectively scavenge free radicals and inhibit autoxidation, thereby extending the shelf life and stability of sensitive materials. It is primarily needed by manufacturers in the polymer, rubber, and specialty chemical industries, where it serves as a crucial additive to prevent premature degradation and ensure product consistency during processing and storage.

Application

• Polymer Stabilizer: Used as an antioxidant in polyolefins (e.g., polyethylene, polypropylene) and other polymers to prevent thermal and oxidative degradation during extrusion and molding.
• Rubber Industry: Acts as an antiozonant and antioxidant in synthetic rubber and elastomer formulations to enhance durability and resist cracking.
• Fuel & Lubricant Additive: Employed in fuels, oils, and greases to inhibit gum formation and oxidative breakdown, improving performance and engine life.
• Chemical Intermediate: Serves as a key building block in the synthesis of more complex antioxidants and hindered phenol derivatives.
• Adhesive & Sealant Formulations: Incorporated to prevent viscosity increase and maintain adhesive properties by inhibiting polymerization.
• Pharmaceutical & Cosmetic Preservative: Functions as a stabilizing agent in specific formulations to protect active ingredients from oxidative degradation.

Quality Control

Our 4,6-Di-tert-Butyl-3-Methoxycatechol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent industry specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your quality requirements.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flame.
