Quality Control

Our Benzenesulfonic Acid, 4-Ethenyl-3-Ethyl- (9Ci) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the material should be stored in a cool, dry place with controlled humidity. For long-term stability, storage at 2-8°C under an inert atmosphere is recommended. Keep the container tightly sealed when not in use to prevent moisture absorption and decomposition.
