Glycolaldehyde is the organic compound with the formula HOCH 2 −CHO. It is the smallest possible molecule that contains both an aldehyde group (−CH=O) and a hydroxyl group (−OH). It is a highly reactive molecule that occurs both in the biosphere and in the interstellar medium. It is normally supplied as a white solid.
A chemical reaction of various salicylaldehydes (2-hydroxybenzaldehydes) with (E)-N-methyl-1-(methylthio)-2-nitroethenamine, in the presence of a basic ionic liquid catalyst such as choline hydroxide, at room temperature in an aqueous medium, produces 2-amino-3-nitro-4H-chromene derivatives (yields up to 83-96%).
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
