Quality Control

Every batch of our Bicyclo[4.4.1]Undeca-1,3,5,7,9-Penten-11-One is produced and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, GC, NMR, and MS to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specification parameters is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C/59-77°F). Due to its sensitivity, the material should be stored under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat, sparks, and open flame.
