2-Methylbutyraldehyde

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.
