Quality Control

Our 7-Isopropyl-2,4-Dimethylazulene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR). We provide a Certificate of Analysis (COA) with every shipment, detailing all critical specifications to ensure it meets the rigorous standards required for research and industrial synthesis.

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 easily oxidized and light-sensitive; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain purity and color integrity.
