Adipaldehyde

Adipaldehyde is the organic compound with the formula (CH₂)₄(CHO)₂. It is a colorless oil that is usually encountered as an aqueous solution because it is highly reactive like many dialdehydes.^[1] The compound has attracted interest as a precursor to nylon-related polymers. It can be produced by double hydroformylation of 1,3-butadiene, but this methodology has not achieved commercialization.^[2] It has been prepared by oxidation of 1,6-hexanediol with pyridinium chlorochromate.^[3]
