Quality Control

Our 1-Fluoro-2-Isocyanatoethane is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support custom synthesis and can tailor purity grades to meet specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place, away from heat, sparks, and open flame. Due to its highly volatile and moisture-sensitive nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) at temperatures between 2°C and 8°C for long-term stability. Allow the sealed container to reach ambient temperature before opening to prevent moisture ingress.
