Quality Control

Every batch of 2-Cyclobutene-1,2-Dicarbonylchloride,3-Methyl-(6Ci) is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the precise requirements for research and scale-up. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended long-term storage temperature is 2-8°C.
