Quality Control

Every batch of 3-(Dotetracontenyl)Succinic Anhydride is manufactured under a strict quality management system and undergoes comprehensive analytical testing to ensure consistency and purity. Our standard industrial grade meets rigorous in-house specifications, with key parameters including assay, acid value, and saponification value. A Certificate of Analysis (COA) documenting these results is provided with each shipment to guarantee traceability and 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/59-77°F). This material is hygroscopic (moisture-sensitive); ensure containers are kept sealed when not in use to prevent degradation from atmospheric moisture. Keep away from strong bases, oxidizing agents, and sources of heat.
