Quality Control

Every batch of our (11Bs)-(+)-4,4-Dibutyl-4,5-Dihydro-2,6-Bis(3,4,5-Trifluorophenyl)-3H-Dinaphth[2,1-C1#,2#-E]Azepinium Bromide is manufactured and analyzed under strict quality management systems. We provide comprehensive analytical data to ensure identity, purity, and chiral integrity for your critical applications. Certificates of Analysis (COA) detailing specifications such as chiral purity (enantiomeric excess), chemical purity (HPLC), and residual solvents are available upon request and can be tailored to meet specific project or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment. For long-term storage, consider storing under an inert atmosphere (e.g., nitrogen or argon) to maintain optimal stability.
