Burca, Ion published the artcile5-((8-Hydroxyquinolin-5-yl)diazenyl)-3-methyl-1H-pyrazole-4-carboxylic acid, HPLC of Formula: 23286-70-6, the publication is Molbank (2021), M1238, database is CAplus.
A new azo compound I was prepared via the azo coupling reaction between 4-(ethoxycarbonyl)-3-methyl-1H-pyrazole-5-diazonium chloride II and 8-hydroxyquinoline (oxine). The ester functional group of the obtained compound I was hydrolyzed and thus a new chem. structure with a carboxylic functional group III was resulted. The structures of the new compounds were fully characterized by: UV-Vis, FT-IR, 1D and 2D NMR spectroscopy, and HRMS spectrometry.
