Reactivity
2,3,4,6-TETRACHLOROPHENOL reacts as a weak organic acid and is incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. May generate heat with bases. Such heating may initiate polymerization.
