Quality Control

Our 5-Methyl-3-heptene is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, ideally at 2-8°C or as specified on the label. Keep away from heat, sparks, and open flames. Containers must be kept tightly sealed when not in use to prevent evaporation and potential concentration of peroxides over time.
