Succinaldehyde or succindialdehyde is an organic compound with the formula (CH2CHO)2. Typical of other dialdehyde, 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[edit]

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]
