Description

3,7-Dioctyl-10H-Phenothiazine is a substituted phenothiazine derivative, a chemical class renowned for its electron-donating and radical-scavenging properties. This compound is valued for its enhanced lipophilicity and stability, making it a critical functional additive in advanced material formulations. It is primarily sought by manufacturers in the polymer, lubricant, and specialty chemical industries seeking to improve product longevity and performance under oxidative stress.

Application

• Polymer Stabilizer: Acts as a highly effective antioxidant and radical scavenger in polyolefins (e.g., polyethylene, polypropylene) and other polymers to prevent thermal and oxidative degradation during processing and service life.
• Lubricant & Grease Additive: Imparts exceptional oxidative stability to synthetic and mineral-based lubricants, extending drain intervals and protecting machinery components under high-temperature operation.
• Fuel & Petrochemical Additive: Used as a stabilizer in fuels, hydraulic fluids, and transformer oils to inhibit gum formation and maintain fluid integrity.
• Photovoltaic & Electronic Materials: Serves as a hole-transport material (HTM) or additive in the research and development of organic solar cells (OSCs) and other organic electronic devices.
• Chemical Intermediate: Utilized in organic synthesis for the preparation of more complex phenothiazine-based compounds with tailored properties for research and industrial applications.

Quality Control

Our 3,7-Dioctyl-10H-Phenothiazine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

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