Quality Control

Our Hexanoyl Chloride, 4-Chloro- is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and identification by FT-IR, to ensure high purity and consistency. Certificates of Analysis (COA) with detailed specifications are provided for every shipment, supporting compliance in cGMP and ISO 9001 environments for intermediate use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and oxidizing agents.
