Meaning and Definition

A ketone with seven carbon atoms in its molecular structure.

Specifically, any of several isomeric organic compounds with the formula C7H14O, characterized by a carbonyl group (C=O) bonded to two alkyl groups, totalling seven carbons. The most common isomers are 2-heptanone and 3-heptanone, used as industrial solvents and in flavor/fragrance applications.

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.

No. It is exclusively a scientific noun referring to a specific chemical. It has no verbal forms and is not used in general conversation.
