Quality Control

Every batch of 5-Octen-7-Yn-2-One, (E)- (9Ci) is produced and tested under strict quality management protocols to ensure consistency and reliability for your research and production needs. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity (by GC or HPLC), identity confirmation (by IR and/or NMR), and impurity profiles. Our commitment to supply chain integrity and traceable documentation supports compliance in regulated research environments.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Isolate from strong oxidizing agents. Due to its sensitivity, the container should be kept tightly sealed and allowed to reach ambient temperature before opening to minimize moisture ingress and oxidation.
