Quality Control

Our (E)-2-Isopropyl-5-Methylhex-2-Enal is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing including GC, IR, and NMR to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, confirming compliance with agreed specifications and industry standards for flavor and fragrance ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at 2-8°C (refrigerated) or as specified on the label. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and minimize headspace in opened containers to preserve quality and prevent degradation.
