Quality Control

Our 3-Ethyl-1-Methyl-1,3-Cyclopentadiene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as identity, purity, and impurity profiles. Our quality systems are designed to meet the stringent requirements of research and industrial-scale synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
