Methoxycarbonylmethyl-2(l//)-quinoxalinone (220) with p-chlorobenzene-diazonium chloride gave a product, initially formulated as 3-[a-(p-chloro-phenylazo)-a-methoxycarbonylmethylene]-3,4-dihydro-2(l//)-quinoxalinone (221) but later as the tautomeric 3-[a-(p-chlorophenyUiydrazono)-a-methoxy-carbonylmethyl]-2(l//)-quinoxalinone (222) (HCl, H2O, AcOH, <5°C, 10 min, then 95°C, 30 min 90%). ° Such tautomerisms have been studied in some detail.(See also Section 6.6.)... 

Allura red AC (E 129, FD C Red No. 40, Cl Eood Red 17) is a mono azo dye that consists essentially of 6-hydroxy-5-(2-methoxy-5-methyl-4-sulfophenyl) azo-2-naphtalenesulfonic acid sodium salt (or disodium 2-hydroxy-l-(2-methoxy-5-methyl-4sufonato-phenylazo)-naphthalene-6-sulfonate). The calcium and potassium salts are also permitted. 

A copper(II) complexes of 5-phenylazo-3-methoxy salicylidene thiosemicarbazone has been shown to have promising growth inhibition activity against P388 lymphocytic leukemia cells sensitive and resistant to adriamycin [196], The complex involves ON coordination of two deprotonated ligands and v(CS) is reported to be unaltered in intensity and position in the complex from its position in the spectrum of the ligand. Inhibition studies with the uncomplexed thiosemicarbazone indicating an important role for the copper(II).
