Quality Control

Our Diethyl Succinosuccinate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and impurity profiles. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, moisture content, and residual solvents. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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). Keep away from strong bases and incompatible materials such as strong oxidizing agents. The container should be kept tightly sealed when not in use to prevent contamination and moisture absorption.
