Quality Control

Our Methacrylate CAS NO 18358-13-9 is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and assay, to ensure it meets exacting industry and customer specifications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, containers must be kept tightly sealed when not in use and away from heat, sparks, and open flame. Keep away from incompatible materials such as strong oxidizing agents.
