Quality Control

Our 3,4-Bis(2-Fluoroethoxy)-Benzaldehyde is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) with full analytical data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term storage. Keep away from strong oxidizing agents.
