Reactivity
ALDRIN, LIQUID is a chlorinated diene. May be sensitive to prolonged exposure to light. Stable to heat and in the presence of inorganic and organic bases. Stable with hydrated metal chlorides and mild acids. Reacts with concentrated acids and phenols in the presence of oxidizing agents. Can react with acid catalysts, acid oxidizing agents and active metals (NTP, 1992).
