Azobenzene 4,4 -dimethoxy

Oxidation of the syringic acid is considered to result in the formation of an unstable semiquinone, which undergoes decarboxylation with concurrent uptake of O2 to form the 2,6-dimethoxy-l,4-benzoquinone (41). The third peak from 475 to 521 ppm, with maxima at 483, 504, and 515 ppm, corresponds to azobenzene nitrogens. These most likely arise from nitrogen to nitrogen coupling reactions between the anilino radicals and free aromatic amino groups in the fulvic acid molecules ...
