Quality Control

Our Trans,trans-2,4-Decadienal is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including GC, HPLC, and IR spectroscopy. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its nature as an unsaturated aldehyde, it is easily oxidized and should be handled under an inert atmosphere for long-term storage to maintain optimal stability and shelf life.
