Quality Control

Our 1-Methylidenecyclododecane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques (GC, GC-MS, NMR) to confirm identity and quantify purity and potential impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your material specifications.

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 area at room temperature (15-25°C). Due to its easily oxidized nature, minimize headspace and exposure to air after opening. Keep away from heat, sparks, and open flames.
