| Hazard Information | Back Directory | [Description]
2-Methylbutyraldehyde has a powerful, choking odor with a peculiar cocoa and coffee-like flavor when diluted. It has a sweet,
slightly fruity, chocolate-like taste. May be prepared by oxidation
of sec-butylcarbinol isolated from fermented fusel oil; the dl-form
from sec-butyl magnesium bromide and formaldehyde; by reduction of methylethylacetic acid. | [Chemical Properties]

ChEBI: 2-methylbutanal is a methylbutanal in which the methyl substituent is at position 2. It has a role as a volatile oil component, a plant metabolite and a Saccharomyces cerevisiae metabolite. It is a 2-methyl-branched fatty aldehyde and a methylbutanal. | [Preparation]
By oxidation of sec-butylcarbinol isolated from fermented fusel oil; the dl-form from sec-butyl magnesium bromide and
formaldehyde; by reduction of methylethylacetic acid | [Taste threshold values]
characteristics at 10 ppm: green, fruity, musty with a berry nuance, musty, furfural and rummy, with
nutty and cereal notes, caramel and fruity undernotes. | [General Description]
2-Methylbutyraldehyde has been identified as one of the important flavor compounds in barley crystal malts, baked potatoes, whole milk powder (WMP). |
