| Hazard Information | Back Directory | [Description]
3-(Methylthio)butanal has the flavor of potato chips. It is prepared
by addition of methanethiol to the corresponding unsaturated aldehyde
(previously cooled to -20°C), using piperidine or copper
acetate as catalyst; by a patented oxo process. | [Chemical Properties]
3-Methylthiobutyraldehyde has a green, musky, buchu odor and a flavor reminiscent of potato chip | [Occurrence]
Reported found in French fried potato and krill. | [Uses]
3-(Methylthio)butanal, is shown to be used as flavoring and fragrances agent. It is also used as a starting material for the synthesis of Sulfoxaflor (S755005), which is an insecticide . | [Definition]
ChEBI: 3-(Methylthio)butanal is an aldehyde. | [Preparation]
By addition of methanethiol to the corresponding unsaturated aldehyde (previously cooled to -20°C), using piperidine or
copper acetate as catalyst; by a patented oxo process | [Taste threshold values]
