FAQ
Frequently Asked Questions
It is generally considered low in toxicity but is flammable and can be an irritant; safety data sheets (SDS) for the specific isomer should always be consulted.
In industrial settings as a solvent, in some cleaning products, or as a component in artificial flavourings and fragrances (e.g., blue cheese).
Heptane (C7H16) is a saturated hydrocarbon (alkane) with only single bonds. Heptanone (C7H14O) is a ketone, containing a carbonyl (C=O) functional group, making it more reactive and polar.
