Quality Control

Our 4-n-Butoxybenzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration and impurity profiling by chromatographic methods (HPLC/GC), to ensure high chemical purity and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and reacts vigorously with water, alcohols, and bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent hydrolysis. Isolate from strong oxidizing agents, strong bases, and sources of moisture.
