Occurrence

Reported found in tomato, potato chips, coffee and malt.

Definition

ChEBI: (methylsulfanyl)acetaldehyde is an aldehyde that is acetaldehyde in which one of the methyl hydrogens has been replaced by a methylsulfanyl group. It is an aldehyde and a methyl sulfide. It is functionally related to an acetaldehyde.

Preparation

By hydrolysis of the diethyl acetal of 2-methyl thioacetaldehyde with diluted HCl; the diethyl acetal is prepared from diethylbromoacetal treated with sodium methyl mercaptide
