Quality Control

Our 2-Isopropyl-5-Methylhex-4-Enal is produced under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for sensitive fragrance and flavor applications. Each lot is analyzed against stringent internal specifications, which typically include assessment of identity, assay, and key impurities. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and light-sensitive, it is recommended to keep the container under an inert gas blanket (e.g., nitrogen) after opening and minimize exposure to air and light during handling.
