Quality Control

Our 1,1-Dichlorocyclobutane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (NMR, IR), to verify identity and purity. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, bases, and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to prevent moisture absorption and volatilization.
