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. It is used as a crosslinking agent but is less widely used than the related dialdehyde glutaraldehyde.
