Anwendungen

Precursor to a variety of chelating agents.Salicylaldehyde is used as a precursor to prepare catechol, benzofuran, salicylaldehydimine and 3-carbethoxycoumarin. It is used for colorimetric assay of isoleucine as well as utilized for the determination of primary amine by fluorescence method. It is a key starting material to a various chelating agents. It is used as flavor and fragrance components. Its derivative salicylaldehyde thiosemicarbazone is used for the simultaneous determination of molybdenum and iron by spectrophotometric method.

Bemerkungen

Incompatible with acids, strong reducing agents, strong oxidizing agents, strong bases and halogens.
