Quality Control

Our Trimethylsilyl Perfluoroheptanoate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

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). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed after opening to minimize exposure to moisture and prevent evaporation. Keep away from incompatible materials such as strong bases and oxidizing agents.
