Quality Control

Our 3-Methyl-2-cyclopentene-1-thione is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and structural confirmation, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing specific results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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 or argon) for long-term preservation and to minimize decomposition.
