Quality Control

Every batch of 1,2-Dichlorotetrafluorocyclobut-1-Ene is produced and tested under stringent quality management protocols. We ensure compliance with relevant industry standards for high-purity chemical intermediates. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles—typically determined by GC, GC-MS, and NMR—is provided with each shipment to guarantee consistent quality and traceability for your critical R&D and production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from sources of ignition, strong bases, and reactive metals. Due to its high volatility, ensure containers are kept upright and sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability.
