Quality Control

Our Di-sec-Butylphenol is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, color, and moisture content. Our quality commitment ensures the product meets the specifications required for your specific industrial application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its nature of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain optimal quality. Keep container tightly sealed when not in use.
