Quality Control

Our Bis[1-(Methylphenyl)Ethyl]Phenol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent performance as a polymer stabilizer. Certificates of Analysis (COA) detailing purity, identity, and key physical 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 room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve efficacy. Keep away from strong oxidizing agents.
