Description

Dibutyl 2,6-Di-tert-Butyl-4-Tolyl Orthoborate is a specialized organoboron compound used as a key intermediate and additive in advanced chemical synthesis. Its value lies in its unique sterically hindered phenolic structure, which provides excellent stability and performance in demanding applications. This product is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product longevity and performance under oxidative stress.

Application

• Polymer Stabilizer: Acts as a highly effective antioxidant and light stabilizer in polyolefins (e.g., polyethylene, polypropylene) and other polymers to prevent thermal and UV degradation.
• Lubricant Additive: Used in formulating high-performance synthetic lubricants and greases to improve oxidative stability and extend service life.
• Chemical Intermediate: Serves as a crucial building block in the synthesis of more complex hindered phenol antioxidants and other specialty boron-containing compounds.
• Fuel Additive: Employed in gasoline and diesel formulations to inhibit gum formation and stabilize fuels during storage.
• Rubber Industry: Provides anti-aging properties in elastomers and synthetic rubbers, protecting against cracking and loss of elasticity.
• Adhesive & Sealant Formulations: Enhances the long-term stability and durability of high-performance adhesives and sealants.

Quality Control

Our Dibutyl 2,6-Di-tert-Butyl-4-Tolyl Orthoborate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available for all shipments to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to minimize exposure to moisture and air.
