Quality Control

Our Isobutenyl Succinic Anhydride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, reactivity, and consistency. A comprehensive Certificate of Analysis (COA) documenting identity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from strong acids and incompatible organic solvents.
