Quality Control

Our 1,4-Dimethylbutane-1,4-Diyl Bismethacrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by HPLC and impurity profiling, to ensure it meets the high-purity standards required for sensitive applications like medical and optical materials. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flames. For long-term storage, consider under an inert gas such as nitrogen.
