Ward, Cassandra L.;Allen, Matthew J.;Lutter, Jacob C. published 《Hexa-μ-acetato-chlorido(μ-N,2-dioxodobenzene-1-carboximidato)-μ₃-oxido-tetrairon(III)-water (1/1) and hexa-μ-acetato-(μ-N,2-dioxodobenzene-1-carboximidato)fluorido-μ₃-oxido-tripyridinetetrairon(III)-pyridine-water (1/1/0.24)》 in 2021. The article was appeared in 《Acta Crystallographica, Section E: Crystallographic Communications》. They have made some progress in their research.Application In Synthesis of N,2-Dihydroxybenzamide The article mentions the following:

The title compounds, [Fe₄(C₂H₃O₂)⁶(C₇H₄O₃)FO(C₅H₅N)₃]·C₅H₅N·0.24H₂O (1-F) and [Fe₄(C₂H₃O₂)₆(C₇H₄O₃)ClO(C₅H₅N)₃]·H₂O (1-Cl) were synthesized using a self-assembly reaction in methanol and pyridine with stoichiometric addition of salicylhydroxamic acid , acetic acid (HOAc), and the appropriate ferric halide salt. The compounds crystallize as solvates, where 1-F has one pyridine mol. that is disordered about a twofold axis and one water mol. with an occupancy of 0.24 (2); and 1-Cl has one water mol. that is disordered over two sites with occupancies of 0.71 (1) and 0.29 (1). The space groups for each analog differ as 1-F crystallizes in Fdd2 while 1-Cl crystallizes in P2₁. The difference in packing is due to changes in the intermol. interactions involving the different halides. The two mols. are mostly isostructural, differing only by the torsion of the pyrine ligands and slight orientation changes in the acetate ligands. All of the iron(III) ions are in six-coordinate octahedral ligand field geometries but each one exhibits a unique coordination environment with various numbers of O (four to six) and N (nought to two) atom donors. Bond-valence sums confirm each iron is trivalent. The hydroximate ligand is bound to three iron(III) ions using a fused chelate motif similar to those in metallacrown compounds The experimental procedure involved many compounds, such as N,2-Dihydroxybenzamide (cas: 89-73-6) .

N,2-Dihydroxybenzamide(cas: 89-73-6) has also been shown to be active against wild-type strains of Candida glabrata, but not against resistant mutants. Application In Synthesis of N,2-Dihydroxybenzamide This drug may have therapeutic potential for bone cancer and metabolic disorders such as obesity.

Cao, Shiming;Cao, Yijun;Ma, Zilong;Liao, Yinfei;Zhang, Xiaolin published 《Structural and electronic properties of bastnaesite and implications for surface reactions in flotation》. The research results were published in《Journal of Rare Earths》 in 2020.Recommanded Product: N,2-Dihydroxybenzamide The article conveys some information:

The structural and electronic properties of bastnaesite were studied by using the first-principles method based on the d. functional theory (DFT). The geometry structure of bastnaesite was first optimized, and then the Mulliken populations, electron d. and d. of states were calculated and further analyzed in detail. The calculation results reveal that it mainly ruptures along the ionic Ce-O and Ce-F bonds during the cleavage of bastnaesite, leaving ≈Ce⁺, ≈F^– and ≈CO^–₃ dangling bonds exposed on the cleavage surface of bastnaesite. Combined with contact angle measurement, surface complexation theory and XPS anal., the implications of structural and electronic properties on bastnaesite flotation reactions were studied. The hydration of exposed strong ionic bond on cleavage surface results in hydrophilic surface. According to surface complexation theory, the formed surface groups are ≈CeOH⁰, ≈CO₃H⁰ and ≈FH⁰ groups. The investigated metal ions and flotation reagents complex with surface ≈CeOH⁰ groups, while ≈CO₃H⁰ and ≈FH⁰ groups are not involved in the complexation. The high activity of Ce atoms facilitates these surface reactions.N,2-Dihydroxybenzamide (cas: 89-73-6) were involved in the experimental procedure.

N,2-Dihydroxybenzamide(cas: 89-73-6) is widely used for a variety of roles in biology and medicine as a chelating therapy.Recommanded Product: N,2-DihydroxybenzamideIt inhibits bacterial or fungi growth by interfering with iron uptake. It is also active as a inhibitor of enzyme involved in tumour growths.
