Quality Control

Our 11-Fluoroundecanoic Acid Trimethylsilyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, NMR, and FTIR, to ensure high chemical purity and identity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee reproducible performance in your synthetic applications.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong acids and oxidizing agents.
