Quality Control

Our Ethanone, 1-(4-Methyl-7-Oxabicyclo[2.2.1]Hept-5-En-2-Yl)-, Endo- (9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC and structural confirmation by NMR/IR spectroscopy, to ensure it meets the exacting standards required for research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, ensure the container is properly sealed after each use to minimize headspace exposure.
