Quality Control

Every batch of our 2-[[(2-Methyl-1-Oxoallyl)Oxy]Methyl]-2-Propyl-1,3-Propanediyl Bismethacrylate is manufactured under a strict quality management system. We ensure high purity and consistent performance through rigorous analytical testing, including HPLC, GC, and NMR. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to guarantee compliance with your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 15-25°C under an inert atmosphere (e.g., nitrogen) to prevent oxidation and polymerization. Keep away from heat, sparks, and open flame. For long-term storage, refrigeration at 2-8°C is recommended to maintain optimal stability.
