Quality Control

Our Methyl Ester L-Lysine Diisocyanate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and production. A comprehensive Certificate of Analysis (COA) detailing purity, isomeric content, and residual solvent levels is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its moisture-sensitive and light-sensitive nature. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and water.
