Quality Control

Our Sodium 1-Octadecyl-5-Oxopyrrolidine-3-Carboxylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
