Quality Control

Our (2-Methyl-5-Prop-2-Ynyl-3-Furyl)Methyl 2,2-Dimethyl-3-(2-Methylprop-1-Enyl)Cyclopropane-1-Carboxylate is produced under strict quality management systems to ensure batch-to-batch consistency and high purity, meeting the rigorous demands of industrial synthesis. Quality is verified through advanced analytical techniques including HPLC, GC, and NMR. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C/59-77°F). This material is light-sensitive and should be stored away from direct light. It is also easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen or argon) to preserve stability. Keep away from strong acids and incompatible organic solvents.
