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. PreparationSuccinaldehyde 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] References1. ^{{US patent|2710883}} 2. ^Hardy, P.
