Quality Control

Our 4-Pentylbenzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure it meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and consistent quality.

Storage

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