Quality Control

Our 2-Octadecenal is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your research or production requirements.

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 area at room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace in opened containers and handle under inert gas when possible.
