A seven-carbon ketone compound, commonly 2-heptanone, which is a colorless liquid used as a solvent.
From Greek 'hepta' (seven) + 'one' (ketone suffix, from 'acetone'). Systematically named for the seven-carbon chain and ketone functional group.
2-heptanone is used to thin paint and as a solvent for industrial processes, but it's also found naturally in human sweat—it's one of the chemicals that makes body odor smelly.
