Quality Control

Our 4-n-Decylbenzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure high chemical purity and consistency. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with strong bases and nucleophiles; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent hydrolysis. Keep away from heat, open flames, and incompatible materials such as water, alcohols, amines, and strong oxidizers.
