Quality Control

Our sec-Butyl Disulfide is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specified parameters. Our quality commitment ensures the product meets the requirements for use as a reliable intermediate in sensitive chemical syntheses.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This compound is easily oxidized; for long-term storage or after opening, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve stability and purity. Keep away from strong oxidizing agents, heat, and ignition sources.
