Quality Control

Our 4-Oxo-Pentoyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of our global B2B clients. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
