Quality Control

Our Dihydro-2-Methyl-5-Pentyl-3(2H)-Furanone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and HPLC analysis, to ensure high purity and consistent organoleptic quality. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen) to maintain optimal stability and shelf life. Keep away from strong oxidizing agents.
