Quality Control

Our 2,6-Dioctylphenol is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure it meets precise purity and composition specifications. A Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with each shipment, ensuring traceability and compliance for your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
