Quality Control

Our Nonafluoro-1-Butanesulfinic Acid Trimethylsilyl Ester is manufactured under stringent quality systems. Each batch undergoes comprehensive analytical testing, including NMR (1H, 19F, 13C), GC, and HPLC analysis, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C or as specified on the label. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
