Usage: o-Phenylenediamine (O-PDA) is intermediate used in the synthesis of insecticides, dyestuff, fungicides, corrosion inhibitors, pigments and pharmaceuticals; o-Phenylenediamine (O-PDA) is also used to remove elemental sulfur in mining ores, and to remove aldehye color formers in polymeric.
In coordination chemistry, o-Phenylenediamine (O-PDA) is an important ligand precursor. Schiff base derivatives, such as those derived from salicylaldehyde, are excellent chelating ligands. Oxidation of its metal-phenylenediamine complexes affords the diimine derivatives, which are intensely coloured and often exist in multiple stable oxidation states.
Package and storage: 25kg drum or bag, Keep in the clear and dry storage shed.
