Quality Control

Our 1-Iodoheptafluorobut-1-Ene is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for research and industrial use. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as purity (by GC or NMR), identity confirmation, and impurity profiles. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area, ideally between 2°C and 8°C to minimize volatility and degradation. Due to its highly volatile and light-sensitive nature, containers should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use and allowed to equilibrate to room temperature before opening to prevent moisture ingress.
