Quality Control

Our Bicyclo[2.2.1]Hepta-2,5-Diene-2-Carboxylic Acid, 3-Methyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent lot-to-lot 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, well-ventilated area at a controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent, keep away from incompatible materials such as strong bases, oxidizing agents, and amines. For long-term storage, consider an inert atmosphere to preserve stability.
