Quality Control

Our 1,2-Dimethylcyclopentene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as identity, assay, and impurity profile. We are committed to meeting the stringent requirements of research and industrial applications, with quality systems designed to support regulatory compliance.

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. Keep container tightly sealed when not in use to prevent evaporation and potential oxidation.
