Quality Control

Every batch of 2-Chlorotetrafluoroethylsulphurpentafluoride is produced and tested under stringent quality management protocols. We ensure compliance with relevant industry standards for high-purity intermediates. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area, preferably at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flames. Containers must be kept tightly sealed when not in use to prevent evaporation and potential moisture ingress.
