Safety Data Sheet

Getting an SDS for Isobutyl 2-(4-(4-chlorophe…

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 Isobutyl 2-(4-(4-chlor… 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.
