Quality Control

Every batch of [R,(+)]-1,2-Cyclononadiene is produced and analyzed under strict quality management protocols. We guarantee high enantiomeric excess (ee) and chemical purity, verified by advanced analytical techniques including chiral HPLC, GC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profile is provided with each shipment to ensure traceability and compliance with your research or production standards.

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 place. Due to its highly volatile and easily oxidized nature, it is recommended to store at 2-8°C for extended stability. Keep away from heat, sparks, and open flames.
