Description

10-Benzyl-3,7-Bis(1,1,3,3-Tetramethylbutyl)-10H-Phenothiazine is a high-performance, sterically hindered phenothiazine derivative valued for its exceptional antioxidant and radical scavenging properties. This compound is engineered to provide superior stabilization in demanding environments where thermal and oxidative degradation are primary concerns. It is a critical additive for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product longevity and performance under stress.

Application

• Polymer Stabilizer: Acts as a highly effective antioxidant and light stabilizer in polyolefins (e.g., PP, PE), engineering plastics, and synthetic rubbers to prevent thermal-oxidative degradation during processing and end-use.
• Lubricant & Fuel Additive: Used as an antioxidant additive in synthetic lubricants, greases, and industrial oils to inhibit sludge formation, viscosity increase, and acid generation, thereby extending service life.
• Specialty Chemical Intermediate: Serves as a key building block for synthesizing more complex stabilizers, dyes, and pharmaceutical agents due to its reactive phenothiazine core.
• Adhesive & Sealant Formulations: Incorporated to prevent premature curing and maintain viscosity stability in polyurethane and other reactive adhesive systems.
• Photographic & Imaging Chemicals: Utilized in certain specialized photographic developers and electrochromic materials for its redox-active characteristics.

Quality Control

Our production of 10-Benzyl-3,7-Bis(1,1,3,3-Tetramethylbutyl)-10H-Phenothiazine adheres to a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters are provided to guarantee the material meets your specific technical requirements and supports your own quality assurance protocols.

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 easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Keep away from strong oxidizing agents.
