Succinaldehyde or succindialdehyde is an organic compound with the formula (CH₂CHO)₂. Typical of other dialdehydes, succinaldehyde is highly reactive. Usually, it is handled as the hydrates or methanol-derived acetal. It is a precursor to tropinone.^[1] It is used as a crosslinking agent but is less widely used than the related dialdehyde glutaraldehyde.

Preparation

2,5-Dihydroxytetrahydrofuran, the hydrated form of succinaldehyde.

Succinaldehyde is generated by the oxidation of THF with chlorine followed by hydrolysis and by the hydroformylation of acrolein derivatives.

In aqueous solution, the molecule hydrates and cyclizes.^[2] In methanol it converts to the cyclic acetal, 2,5-dimethoxyltetrahydrofuran.^[3]
