04 · Handling and storage

Storing and handling α, α,α,4-tetrachlorotoluene

Reactivity

Simple aromatic halogenated organic compounds, such as ALPHA, ALPHA, ALPHA, PARA-TETRACHLOROTOLUENE, are very unreactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Safety Data Sheet

Getting an SDS for α, α,α,4-tetrachlorotoluen…

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 α, α,α,4-tetrachloroto… 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.
