04 · Handling and storage
Storing and handling Heptan-2-one
Incompatible materials
Strong acids, alkalis, and oxidizers (Note: Will attack some forms of plastic).
Source: Hazardous Substances Data Bank (HSDB)
Reactivity
N-AMYL METHYL KETONE reacts exothermically with many acids and bases to produce flammable gases (e.g., H2). The 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 and heat. Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. Incompatible with many oxidizing agents including nitric acid, nitric acid/hydrogen peroxide mixture, and perchloric acid. May form peroxides (USCG, 1999).

Safety Data Sheet
Getting an SDS for Heptan-2-one
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Heptan-2-one issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
