Common Name

2,6-Dimethyl-4-heptanone

Description

2,6-Dimethyl-4-heptanone, also known as isobutyl N-propyl ketone or diisobutyl ketone, belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. 2,6-Dimethyl-4-heptanone is a flavouring ingredient belonging to the family of Ketones. 2,6-Dimethyl-4-heptanone is a banana, fruity, and green tasting compound. 2,6-Dimethyl-4-heptanone is a potentially toxic compound.
