Product Description
1,2-Diformyloxyethane, also known as acetoacetaldehyde or acetate acetaldehyde, is a chemical compound with the molecular formula C4H6O3. It is an acetal compound consisting of two formyl (aldehyde) groups bonded to a central oxygen atom. 1,2-Diformyloxyethane can be synthesized by reacting formaldehyde (CH2O) with acetaldehyde (C2H4O) in the presence of an acid catalyst. It is a colorless liquid with a fruity odor. 1,2-Diformyloxyethane can be used as an intermediate in organic synthesis and as a solvent or reagent in certain reactions. It can also be used as a flavoring agent in the food industry. However, it is very important to handle this compound with care as it is flammable and may irritate the eyes, skin and respiratory system if not handled properly.
