Quality Control

Every batch of 2-Butanone, 4-Fluoro-3-(Fluoromethyl)-3-Methyl- (9Ci) is produced and tested under strict quality management protocols. We provide comprehensive analytical data to ensure identity, purity, and consistency for your critical R&D and scale-up processes. A detailed Certificate of Analysis (COA) including assay (typically by GC or HPLC), identity confirmation (IR, NMR), and impurity profile is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature: 2-8°C for long-term stability.
