Description

3,5-Di-tert-Butyl-4-Hydroxybenzyl Alcohol is a sterically hindered phenolic compound that serves as a versatile intermediate in organic synthesis. Its molecular structure, featuring a phenolic hydroxyl group and a benzylic alcohol, makes it a valuable building block for the production of high-performance antioxidants and light stabilizers. This compound is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance the durability and longevity of their products.

Application

• Primary Antioxidant Intermediate: A key precursor in the synthesis of high-molecular-weight phenolic antioxidants (e.g., Irganox 1010 analogs) for plastics and polymers.
• Polymer Additive Synthesis: Used to manufacture light stabilizers and UV absorbers that protect polymers like polyolefins, PVC, and engineering plastics from oxidative degradation.
• Lubricant and Fuel Additives: Incorporated into formulations to improve the oxidative stability of industrial lubricants, greases, and fuels.
• Rubber Industry: Acts as an intermediate for antioxidants used in synthetic rubber (SBR, BR) and elastomers to prevent cracking and aging.
• Specialty Chemical Synthesis: Serves as a building block for creating complex molecules used in agrochemicals and pharmaceutical intermediates.
• Coating Stabilizers: Utilized in the production of additives that protect paints, coatings, and adhesives from yellowing and loss of gloss due to heat and light exposure.

Quality Control

Our production of 3,5-Di-tert-Butyl-4-Hydroxybenzyl Alcohol adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request, providing full traceability and compliance assurance for your quality systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive and easily oxidized; prolonged exposure to air and light should be avoided. For long-term storage, consider an inert atmosphere (e.g., nitrogen) to maintain optimal purity.
