Quality Control

Our Butyl Methanethiosulfonate is produced under stringent 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. Certificates of Analysis (COA) with detailed specifications are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be amber-colored or stored in opaque secondary packaging.
