Safety Data Sheet

Getting an SDS for 2-Ethyl-1-(2-(1,3-dioxanyl…

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 2-Ethyl-1-(2-(1,3-diox… 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

2-Ethyl-1-(2-(1,3-dioxanyl)eth… precautionary statements

CLP Annex VI assigns 2 precautionary statements to 2-Ethyl-1-(2-(1,3-dioxanyl…. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

Prevention

Disposal

What has to happen to the contents and the empty container.
