Safety Data Sheet

Getting an SDS for N,N'-Dimethyl-N,N'-bis(tri…

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of N,N'-Dimethyl-N,N'-bis… issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.

04 · Precautionary statements
