Quality Control

Every batch of 3-Furancarbonyl Chloride, 2,5-Dihydro-5-Oxo- (9Ci) is manufactured and tested under a strict quality management system. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). 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. Keep away from incompatible materials such as strong bases, alcohols, and amines.
