Quality Control

Our (E)-(1-Methylethylidene)Bis(4,1-Phenyleneoxy-2,1-Ethanediyl) Crotonate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC and GC analysis, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its light-sensitive and easily oxidized nature, it is recommended to store this material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
