Description2-[(Methylthio)methyl]-2-butenal, also known as 2-ethylidene methional or fema 3601, belongs to the class of organic compounds known as enals. These are an alpha,beta-unsaturated aldehyde of general formula RC=C-CH=O in which the aldehydic C=O function is conjugated to a C=C triple bond at the alpha,beta position. 2-[(Methylthio)methyl]-2-butenal is an extremely weak basic (essentially neutral) compound (based on its pKa).
