Quality Control

Our production of Cyclopropane, 1-Methylene-2-[1-[(Trimethylsilyl)oxy]ethenyl]- adheres to stringent internal quality standards to ensure batch-to-batch consistency and reliability for critical R&D and scale-up processes. Each lot is characterized by advanced analytical techniques including GC, HPLC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its moisture-sensitive (hygroscopic) nature, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) after opening and should be allowed to reach room temperature before opening to prevent moisture ingress. Recommended long-term storage at 2-8°C.
