Dear Researchers,

I'm currently working with Dimethyl Disulphide (DMDS) in my research project, and I need to ascertain it's purity. The substance I have is reported to be approximately 99.5% pure on a weight basis.

I am seeking guidance on the best techniques or methods to confirm this level of purity. Are there any industry standard or academic lab procedures that I can use? Are there specific pieces of lab equipment that you would recommend?

I appreciate any advice or resources you can provide.

Best regards,

Amir Darban Loghmani
