Quality Control

Our Butylnaphthalene-2-Sulphonic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your 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) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Keep away from strong bases and oxidizing agents.
