Quality Control

Our 1-Ethyl-3-Methylenecyclobutane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR, to ensure high purity and consistent chemical identity. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all relevant specifications. Our commitment to quality supports applications in GMP-compliant research and cGMP environments where traceability and documentation are paramount.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flames. Due to its unsaturated nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize potential polymerization or oxidation.
