Quality Control

Our Sodium Benzotriazolyl Butylphenol Sulfonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee traceability and consistency for your formulation needs. We adhere to industry best practices and can support compliance requirements for relevant global standards.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial opening to prevent absorption of atmospheric moisture, which can affect product performance and flow characteristics.
