Quality Control

Our (Triethylsilyl)Methanethiol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. 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, well-ventilated place, ideally at 2-8°C (refrigerated) to minimize volatility and degradation. Due to its highly volatile and light-sensitive nature, containers should be kept tightly sealed and allowed to reach ambient temperature before opening to prevent moisture ingress.
