Use

3-Heptanone is reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion. Reacts with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. May react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. Irritating vapors and toxic gases may be formed when involved in fire [USCG, 1999].
