Quality Control

Our Diamido-Dpeg(R)11-Diamine is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopic methods, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and other critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption. Recommended long-term storage temperature is 2-8°C.
