Quality Control

Our 5-Azulenecarboxaldehyde (9Ci) is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and identity confirmation. We provide full traceability and detailed Certificates of Analysis (COA) for every shipment, supporting your research, development, and regulatory compliance needs.

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 material is easily oxidized and light-sensitive. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
