1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. The triazole ring is a relatively stable functional group, and the triazole bond can be used for a variety of applications, such as replacing the phosphate backbone of DNA. Many triazoles have antifungal effects: the triazole antifungal drugs include fluconazole, isavuconazole, itraconazole, voriconazole, pramiconazole, ravuconazole, and posaconazole and triazole plant-protection fungicides include epoxiconazole, triadimenol, myclobutanil, propiconazole, prothioconazole, metconazole, cyproconazole, tebuconazole, flusilazole and paclobutrazol.Synthetic Route of C4H3N3O4

A new family of 3d-4f heterometallic coordination polymers assembled with 1H-1,2,3-triazole-4,5-dicarboxylic acid: syntheses, structures and magnetic properties was written by Zou, Ji-Yong;Xu, Na;Shi, Wei;Gao, Hong-Ling;Cui, Jian-Zhong;Cheng, Peng. And the article was included in RSC Advances in 2013.Synthetic Route of C4H3N3O4 This article mentions the following:

Five isostructural copper(II)-lanthanide(iii) heterometallic coordination polymers (CPs), {[Cu2Ln(TDA)2Cl(H2O)4]·2H2O}n [Ln = Gd (Cu-Gd), Tb (Cu-Tb), Dy (Cu-Dy), Ho (Cu-Ho) and Er (Cu-Er)] (H3TDA = 1H-1,2,3-triazole-4,5-dicarboxylic acid), were synthesized under solvothermal conditions and structurally characterized. In these CPs, two neighboring Cu(II) ions are connected via one μ2-Cl to form [Cu2Cl]3+ units, which are further linked into a copper chain through bridging TDA3-. The neighboring copper chains are further connected by lanthanide to form a two-dimensional structure with sql topol. The magnetic properties of the five isostructural heterometallic CPs were studied as well. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6Synthetic Route of C4H3N3O4).
