Quality Control

Our 2-Methylthioacetaldehyde is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC and NMR analysis, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support compliance with global regulatory frameworks such as REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at controlled 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) and minimize headspace in opened containers. Keep away from heat, sparks, and open flames.
