Reaktive GruppeAmines, Phosphines, and Pyridines
Reactivity ProfileTETRAMETHYLMETHYLENEDIAMINE may react vigorously when exposed to oxidizing agents. Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides. Not easily ignited, but may burn when exposed to heat.
Air and Water ReactionsNo rapid reaction with air. No rapid reaction with water.
