Quality Control

Our Dibutylnaphthalene-1-Sulphonic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) documenting key parameters are provided to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and strong acid nature, the container must be kept tightly sealed and away from incompatible materials such as strong bases and oxidizing agents.
