Quality Control

Our production of 2-(Henicosafluorodecyl)Ethane-1-Thiol adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and FTIR to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, specific impurities, and physical data is provided with every shipment to support your quality assurance and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. This material is easily oxidized and moisture-sensitive; prolonged exposure to air should be avoided. Keep away from strong oxidizing agents.
