Quality Control

Our 1H,1H-Nonafluoropentyl p-Toluenesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong acids, bases, and oxidizing agents. Due to its reactivity as an alkylating agent and sensitivity to moisture, it is recommended to handle and store under an inert atmosphere such as nitrogen or argon for long-term stability.
