Quality Control

Our Didecylphenol is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against stringent internal specifications, with key parameters including identity, assay, and impurity profile verified. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements.

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, consider maintaining under an inert atmosphere such as nitrogen to preserve product integrity. Keep away from strong oxidizing agents.
