Quality Control

Our production of 2,4-Hexadienal, 5-Hydroxy-, (E,E)- (9Ci) adheres to stringent internal quality protocols to ensure batch-to-batch consistency and purity. While typically supplied as a high-purity research-grade material, specifications can be tailored to meet specific project requirements, including custom purity levels and isomer ratios. A comprehensive Certificate of Analysis (COA) detailing identity, purity (typically by GC or HPLC), and other critical parameters is provided with every shipment to support your quality assurance processes.

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 place. Recommended long-term storage temperature is 2-8°C. Allow the container to reach ambient temperature before opening to minimize moisture ingress. Keep away from strong oxidizing agents.
