Quality Control

Our 3-Furancarbonyl Chloride, Tetrahydro-5-Oxo- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) with detailed specifications are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong acids and incompatible organic solvents.
