Quality Control

Our 2-Propenoic Acid,1,1'-[1,3-Phenylenebis(Methylene)] Ester is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency and high purity, meeting the specifications required for industrial and advanced material applications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is 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 and easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve quality and prevent polymerization.
