Quality Control

Our 3-Phenyl-6-Bromomethylenetetrahydropyran-2-One is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to exclude moisture. Keep away from incompatible materials.
