04 · Handling and storage
Storing and handling Musk ketone
Storage conditions
Keep container tightly closed in a dry and well-ventilated place.
Source: Hazardous Substances Data Bank (HSDB)
Incompatible materials
Incompatible materials: Strong acids, strong bases.

Reactivity
A nitrated ketone. Ketones are 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 of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.

Safety Data Sheet
Getting an SDS for Musk ketone
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 Musk ketone 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.
