Quality Control

Our 2,3,4,5,6-Pentafluorophenyl 2,5-Dichlorobenzenesulphonate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We adhere to ISO 9001 quality management standards, and our analytical methods include HPLC, GC, and NMR for precise characterization. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your R&D and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled 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) after opening to prevent degradation.
