And the article was included in Organic Letters in 2016.Quality Control of Ethyl 1H-1,2,3-triazole-5-carboxylate This article mentions the following:

An unprecedented conversion of alkenes and enol ethers to the corresponding α-imido carbonyl compounds with excellent regioselectivity and yields has been developed. This oxo-amination process employs readily available N-bromosuccinimide (NBS) and secondary amines as N-sources and DMSO (DMSO) as the oxidant and also leads to the production of amino alcs. in a single step on reduction, thus broadening the scope of this operationally simple reaction. For the first time, the formation of reactive Me₂S⁺-O-Br species generated by the interaction of NBS with DMSO has been proven. In the experiment, the researchers used many compounds, for example, Ethyl 1H-1,2,3-triazole-5-carboxylate (cas: 40594-98-7Quality Control of Ethyl 1H-1,2,3-triazole-5-carboxylate).

Ethyl 1H-1,2,3-triazole-5-carboxylate (cas: 40594-98-7) 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.Triazole heterocyclic structures are found to form many weak nonbond interactions with the receptors and enzymes in biological systems.Quality Control of Ethyl 1H-1,2,3-triazole-5-carboxylate

Co-ligand tuned pyrimidine-2-carboxylate Mn(II) complexes from a 2D 6³ layer to an interpenetrated srs-net was written by Sun, Rui;Gao, Su-Mei;Wang, Shao-Qiang;Song, Wei-Chao;Zhao, Jiong-Peng;Liu, Fu-Chen. And the article was included in Dalton Transactions in 2017.COA of Formula: C4H3N3O4 This article mentions the following:

A 6³ 2D layer complex [Mn₃Cl₃(L₃)]_n·H₂O (1) (L = pyrimidine-2-carboxylate) was obtained by assembling 2-cyanopyrimidine and manganese chloride, in which the L ligands were generated in situ. In 1 six-membered Mn rings were constructed from Mn^II ions and L ligands, which were connected to each other by double chloride anions affording a 2D layer. When the chloride anions in 1 were substituted partly by formate, [Mn₄Cl₃L₄(HCO₂)]_n (2) was obtained. In 2, the L ligands bridge Mn^II to give a 1D chain, which was further connected by the double chloride anions and Cl/formate bridges to form a two-fold interpenetrated srs-net. 2 Exhibits an obvious SHG response of ∼0.8 times that of KDP. Furthermore, 2 is an antiferromagnet with a field induced spin flop transition. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6COA of Formula: C4H3N3O4).

1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. However, triazoles are also useful in bioorthogonal chemistry, because the large number of nitrogen atoms causes triazoles to react similar to azides. Both the triazoles and their derivatives have significant biological properties including antimicrobial, antiviral, antitubercular, anticancer, anticonvulsant, analgesic, antioxidant, anti-inflammatory, and antidepressant activities.COA of Formula: C4H3N3O4

Edge-directed assembly of a 3D 2p-3d heterometallic metal-organic framework based on a cubic Co₈(TzDC)₁₂ cage was written by Tian, Dan;Liu, Sui-Jun;Chang, Ze;Zhang, Ying-Hui;Zhao, Jiong-Peng;Bu, Xian-He.

A three-dimensional (3D) heterometallic metal-organic framework containing cubic-like cages, {[Co₃Na₆(TzDC)₄(H₂O)₆]·7H₂O}_n (1) (H₃TzDC = 1,2,3-triazole-4,5-dicarboxylic acid), was synthesized by the edge-directed self-assembly of TzDC^3-, Co²⁺ and Na⁺ ions. Crystal data reveals that one hydrous Co²⁺ cation is embedded in the central cavity of a cubic-like cage [Co₈(TzDC)₁₂]^20- with eight Co²⁺ cations as the corners and twelve TzDC^3- ligands as the edges. The cages are further bridged by Na⁺ ions to result in a 3-dimensional framework with pcu topol. Magnetic study indicates that besides the spin-orbit coupling of Co²⁺ ions, an antiferromagnetic exchange interaction was found to exist between the Co²⁺ ions in the Co₉ cluster of 1. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6Product Details of 4546-95-6).

Colorimetric Dual Sensors of Metal Ions Based on 1,2,3-Triazole-4,5-Dicarboxylic Acid-Functionalized Gold Nanoparticles was written by Mondal, Palash;Yarger, Jeffery L.. And the article was included in Journal of Physical Chemistry C in 2019.Product Details of 4546-95-6 This article mentions the following:

A simple, rapid, selective, and cost-effective colorimetric assay for Cr³⁺ and Eu³⁺ ion detection has been developed using functionalized gold nanoparticles. Gold nanoparticles (AuNPs) were prepared using HAuCl₄, where sodium citrate is a reducing agent as well as a capping agent, and then functionalized with 1,2,3-triazole-4,5-dicarboxylic acid (TADA). Fourier transform IR (FTIR) and Raman spectroscopies suggested that TADA was functionalized on the surface of AuNPs through the N atom of triazole. The TADA-functionalized gold nanoparticles (TADA@AuNPs) simultaneously detect Cr³⁺ and Eu³⁺ ions from aqueous solution and showed different responses to the two metal ions (Cr³⁺ and Eu³⁺) based on an aggregation-induced color change of AuNPs. They showed a color change from wine red to blue, which was easily detected by the naked eye, as well as by UV-visible and FTIR spectroscopies. The surface plasmon resonance absorbances of Cr³⁺ and Eu³⁺ are 633 and 671 nm, resp., when Cr³⁺ and Eu³⁺ react with TADA@AuNPs and showed good linearity with Cr³⁺ and Eu³⁺ concentrations with detection limits 5.89 nM and 4.30 μM, resp. (S/N = 3). The TADA@AuNPs showed excellent selectivity toward Cr³⁺ and Eu³⁺ compared to those of the 16 different metal ions. We had also tested the selectivity of TADA@AuNPs toward Eu³⁺ compared to that of the other 10 lanthanide systems. Optimal detection was achieved toward Cr³⁺ and Eu³⁺ ions in the pH range 4-10. In addition, TADA@AuNPs were applied to detect Cr³⁺ and Eu³⁺ ions from lake water showing low interference. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6Product Details of 4546-95-6).

1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. The many free lone pairs in triazoles make them useful as coordination compounds, although not typically as haptic ligands. 1,2,3-Triazoles are usually prepared following (3+2) cycloaddition protocols. A common technique for unsubstituted triazoles is the Huisgen azide-alkyne 1,3-dipolar cycloaddition: a azide and an alkyne react at high temperature to form a ring. However, the Huisgen strategy produces a mixture of isomers (typically 1,4- and 1,5-disubstituted) when used to produce substituted triazoles.Product Details of 4546-95-6
