04 · Handling and storage
Storing and handling Diisopropylamine
Storage conditions
Store in a cool, dry, well-ventilated location. Separate from acids; oxidizing material, plastics.
Source: Hazardous Substances Data Bank (HSDB)
Incompatible materials
Strong oxidizers, strong acids.

Reactivity
DIISOPROPYLAMINE can react violently with oxidizing agents and strong acids. Readily eutralizes 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.
