6- (y,y,Dimethylallylammino) purine, (2ip)

6-(γ,γ-Dimethylallylamino)purine (2iP) is a bacteria-derived riboside cytokinin used to grow plant tissues such as tobacco and soybean callus. 2iP is a precursor of the cytokinin Zeatin. 2iP has been used in Schenk and Hildebrandt medium to support in vitro propagation of microshoot cultures from shoot tips of Genista plants.
6-(γ,γ-Dimethylallylamino)purine has been used as a component of Murashige and Skoog medium for promoting tissue lignification in Acca sellowianaand as a component of SIM medium for used in regeneration assay of cotyledons.
