Quality Control

Every batch of Cyclopropane, 1-Chloro-1-Ethynyl-2,3-Dimethyl-, (1Alpha,2Alpha,3Alpha)- (9Ci) undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocols are designed to meet the stringent requirements of research and development applications. Certificates of Analysis (COA) detailing purity (typically by GC or HPLC), identity confirmation (by IR, NMR), and impurity profiles are available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, ideally at controlled room temperature (15-25°C). Keep the container tightly sealed under an inert atmosphere to prevent degradation and minimize evaporation. Store away from heat, sparks, open flames, and oxidizing agents.
