Quality Control

Every batch of (Bromomethyl)Pentafluorosulfur(VI) is produced and analyzed under strict quality management protocols. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles, typically determined by GC, NMR (¹H, ¹⁹F), and IR spectroscopy. Our quality commitment ensures the reagent meets the stringent requirements for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at recommended temperatures between 2°C and 8°C. Due to its moisture-sensitive (hygroscopic) nature, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) and allowed to reach room temperature before opening to prevent condensation and hydrolysis.
