Patent ID: 8288437

Claim:
A tetramethylguanidinium salt of an abscisic acid analog, wherein the abscisic acid analog is selected from the group consisting of the abscisic acid analogs of Structures 1, 2 and 3, wherein (a) for Structure 1: (i) the bond at the 2-position of the side chain is a cis- or trans-double bond; (ii) the bond at the 4-position of the side chain is a trans-double bond or a triple bond; (iii) the stereochemistry of the alcoholic hydroxyl group is S-, R- or an R,S-mixture; (iv) the stereochemistry of the R 1 group is in a cis-relationship to the alcoholic hydroxyl group; and R 1 is ethynyl, ethenyl, cyclopropyl or trifluoromethyl; (b) for Structure 2; (i) the bond at the 2-position of the side chain is a cis- or trans-double bond; (ii) the bond at the 4-position of the side chain is a triple bond; and (iii) the stereochemistry of the alcoholic hydroxyl group is S-, R- or an R,S-mixture; and cc) for Structure 3: (i) the bond at the 2-position of the side chain is a cis- or trans-double bond; (ii) the bond at the 4-position of the side chain is a trans-double bond; and (iii) the stereochemistry of the alcoholic hydroxyl group is S-, R- or an R,S-mixture;
