o-Phthalaldehyde

o-Phthalaldehyde is a dialdehyde consisting of two formyl groups attached to adjacent carbon centres on a benzene ring. It is a building block in the synthesis of heterocyclic compounds and a reagent in the analysis of amino acids. It is used as a disinfectant and as a tanning agent in leather industry. It is useful for the sterilization of endoscopic instruments, thermometers, rubber and plastic equipment which cannot be sterilized by heating system. It is also used as an intermediate in synthesis of pharmaceuticals, medicines, and other organic compounds.
