  • Mesylate salts of heterocyclic cytokinins, compositions containing these derivatives and use thereof
    Patent number: 12570657
    Abstract: Mesylates of heterocyclic cytokinins of general formula I: wherein R is selected from the group comprising C3-C15 cycloalkyl, furfuryl, allyl, 4-hydroxy-3-methylbut-2-en-1-yl, 3-methylbut-2-en-1-yl, 4-hydroxy-3-methylbutyl, 4-hydroxy-1,3-dimethylbut-2-en-1-yl, 4-hydroxy-1,3-dimethylbutyl, benzyl, wherein the cycloalkyl, allyl, benzyl and furfuryl may be unsubstituted or optionally substituted with 1 to 3 substituents selected from the group containing hydroxy, halogen, methyl, hydroxymethyl and methoxy, and salts, solvates and addition salts thereof. These compounds are particularly suitable for agricultural and biotechnological use, and their great advantage is increased water solubility as compared to the corresponding free bases of heterocyclic cytokinins.
