Quality Control

Every batch of 2-Oxotetrahydrofuran-3-Yl Methacrylate is produced and tested under a strict quality management system. We ensure high purity and consistency through comprehensive analytical protocols, including chromatography and spectroscopy. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment. For specific project requirements, custom synthesis and tailored purity grades (e.g., >98% by HPLC) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 2°C and 8°C (refrigerated) to maximize shelf-life and minimize polymerization risk. Due to its highly volatile nature, keep away from heat, sparks, and open flame. Allow the container to reach ambient temperature before opening to prevent moisture condensation.
