Quality Control

Our 2,4-Nonadiene is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Every lot is analyzed using advanced techniques like GC, GC-MS, and IR spectroscopy to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its easily oxidized nature, minimize headspace and exposure to air after opening.
