Quality Control

Our 1H,1H-Perfluoroheptyl p-Toluenesulfonate is manufactured under strict quality management protocols. Each batch is characterized and tested to ensure high purity and consistency, meeting the stringent requirements for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity (typically by NMR and HPLC), identity confirmation, and impurity profiles is provided with every shipment.

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). Keep away from heat, sparks, and open flame. Due to its sensitivity, the container should be kept sealed under an inert atmosphere when not in use to prevent moisture ingress and decomposition.
