Quality Control

Every batch of 3-Ethynyl-2-Fluoroaniline is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation.
