Quality Control

Our 1,2-Dimethyl-1-Cycloheptene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, GC-MS, and NMR to confirm identity and assess purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place, away from heat and ignition sources. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability.
