Quality Control

Every batch of (1,1-Dimethylethyl)(Pentafluorophenyl)Fluorophosphine Sulfide is manufactured and tested under strict quality management protocols to ensure high purity and consistency. Our products undergo rigorous quality testing, including NMR (¹H, ¹⁹F, ³¹P) and HPLC analysis, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, sparks, and open flame.
