Quality Control

Our 5-Phenylpentanoyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration and purity verification via GC/HPLC, to ensure it meets the high standards required for advanced synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability, consistency, and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
