Quality Control

Our production of (2E)-3-(5-Isopropyl-3,8-Dimethylazulen-1-Yl)Acrylic Acid adheres to stringent internal quality standards to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification (NMR, IR). A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation. Keep away from strong acids and organic solvents.
