Quality Control

Our 4,8-Dimethyl-7-Nonen-2-One is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC and IR analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize headspace in partially used containers.
