Quality Control

Our Dodecane-2-Thiol 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 the high standards required for industrial and research applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, identity, and specific impurities. We are committed to consistent quality and supply reliability for our global B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C (refrigerated) for long-term stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
