Quality Control

Our 3,6-Bis[(Chlorocarbonyl)Oxy]Hexahydrofuro[3,2-B]Furan is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment 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). Due to its hygroscopic and moisture-sensitive nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation.
