4,5-Dimethoxy-2-nitrobenzoic acid C??? ??, ??, ??

??? ??

Yellow crystalline powder

??

4,5-Dimethoxy-2-nitrobenzoic acid was used in the synthesis of 4,5-dimethoxy-2-nitrobenzamide and 6,7-dimethoxyquinazoline derivatives.

?? ??

4,5-dimethoxy-2-nitrobenzoic acid in the reaction with organotin oxides/halides yields the organotin carboxylates in anhydrous toluene. The resulting triorganotin carboxylates are one-dimensional polymers that are solid with trigonal bipyramidal geometry, while in solution, they are tetrahedral. Reaction of di-n-butyl tin oxide with 4,5-dimethoxy-2-nitrobenzoic acid yields Tetrabutylbis(4,5-dimethoxy-2-nitro benzoate)Distannoxane Dimer crystallizes as the usual dicarboxylatotetraorganodistannoxane dimer[1-2].

?? ??

4,5-Dimethoxy-2-nitrobenzoic acid is a nitroaromatic compound.
