Succinaldehyde or succindialdehyde is an
organic compound with the formula (CH
2CHO)
2. Typical of other
dialdehydes, succinaldehyde is highly reactive and is rarely observed as the dialdehyde. Usually, it is handled as the hydrates or methanol-derived
acetal. It is a precursor to
tropinone. Succinaldehyde can used as a crosslinking agent for proteins, but it is less widely used than the related dialdehyde
glutaraldehyde.
Preparation and reactions

Succinaldehyde is generated by the oxidation of
tetrahydrofuran with
chlorine followed by hydrolysis of the chlorinated product. It can also be prepared by the
hydroformylation of
acrolein
Acrolein (systematic name: propenal) is the simplest unsaturated aldehyde. It is a colorless liquid with a piercing, acrid smell. The smell of burnt fat (as when cooking oil is heated to its smoke point) is caused by glycerol in the burning fa ...
or the acetals thereof.
In aqueous solution, succinaldehyde quickly converts to the cyclic hydrate. In methanol it converts to the cyclic acetal, 2,5-dimethoxyl
tetrahydrofuran.
