Quality Control

Our 2,3-Dimethyl-1,3-heptadiene is produced and tested under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as identity, assay, and impurity profiles. Our quality systems are designed to meet the rigorous standards required for research and industrial synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Recommended storage temperature is 2-8°C.
