Quality Control

Every batch of Cyclopropene, 3-Methyl-3-[(2-Methylcyclopropyl)Ethynyl]- (9Ci) is produced and tested under stringent quality management protocols to ensure consistency and purity for critical research and production applications. Our quality assurance includes comprehensive analytical characterization using techniques such as GC, HPLC, NMR, and MS. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and impurity profiles against agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Keep away from heat, sparks, and open flames. Due to the reactive nature of the cyclopropene ring, this material should be used promptly after opening the primary container.
