Quality Control

Our production of Cyclohexane, 1,3-Diethynyl-, cis- (9Ci) adheres to stringent quality protocols. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to verify identity, purity, and isomeric composition. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring full traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its nature of being easily oxidized, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place, ideally at 2-8°C for long-term stability. Keep away from heat, sparks, and open flames.
