Description

2,5-Di-tert-Butyl-4-Hydroxyanisole is a high-performance phenolic antioxidant widely used to inhibit oxidative degradation. This compound matters for its effectiveness in stabilizing materials against thermal and oxidative stress, thereby extending product shelf life and maintaining performance integrity. It is primarily needed by manufacturers in the polymer, rubber, lubricant, and food packaging industries where material stability is critical.

Application

• Primary antioxidant in polyolefins (PP, PE) and other polymers to prevent thermal oxidation during processing and service.
• Stabilizer for synthetic rubbers and elastomers to retain elasticity and prevent cracking.
• Additive in industrial lubricants and greases to enhance oxidative stability and extend service intervals.
• Antioxidant in adhesives, sealants, and coatings to protect against degradation from heat and light exposure.
• Stabilizing agent for food-contact polymers and packaging materials (subject to regulatory compliance).
• Intermediate in the synthesis of other specialty antioxidants and chemical compounds.
• Additive in fuel and oil formulations to inhibit gum formation.

Quality Control

Our 2,5-Di-tert-Butyl-4-Hydroxyanisole is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by HPLC and identification by FT-IR, to ensure it meets precise specifications for purity and performance. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its nature as an easily oxidized compound, prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal long-term stability.
