Quality Control

Our [2,2-Bi-1H-Pyrrole]-4-Carboxaldehyde (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. This compound is light-sensitive and easily oxidized; allow the sealed container to reach ambient temperature before opening to minimize moisture ingress and degradation.
