Quality Control

Our 2-Methylallylidene Bismethacrylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) detailing assay, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity, the product should be stored under an inert atmosphere (e.g., nitrogen) to prevent oxidation and moisture absorption. Keep away from heat, sparks, and open flames.
