Gao, Xiang-Jing; Zheng, He-Gen published their research in Dalton Transactions in 2021. The article was titled 《The difference in the CO2 adsorption capacities of different functionalized pillar-layered metal-organic frameworks (MOFs)》.Computed Properties of C5H3Br2N The article contains the following contents:

The excessive use of fossil energy has caused the CO2 concentration in the atm. to increase year by year. MOFs are ideal CO2 adsorbents that can be used in CO2 capture due to their excellent characteristics. Studies of the structure-activity relation between the small structural differences in MOFs and the CO2 adsorption capacities are helpful for the development of efficient MOF-based CO2 adsorbents. Therefore, a series of pillar-layered MOFs with similar structural and different functional groups were designed and synthesized. The CO2 adsorption tests were carried out at 273 K to explore the relation between the small structural differences in MOFs caused by different functional groups and the CO2 adsorption capacities. Significantly, compound 6 which contains a pyridazinyl group has a 30.9% increase in CO2 adsorption capacity compared to compound 1 with no functionalized group. The experimental process involved the reaction of 2,5-Dibromopyridine(cas: 624-28-2Computed Properties of C5H3Br2N)

2,5-Dibromopyridine(cas: 624-28-2) belongs to pyridine. Pyridines are often used as catalysts or reagents; particular notice has been paid recently to how pyridine coordinates to metal centers enabling a wide range of valuable reactions. Computed Properties of C5H3Br2N

Formula: C5H3Br2NIn 2019 ,《The development of improved syntheses of PPARγ-sparing, insulin sensitizing thiazolidinedione-ketones》 was published in Tetrahedron Letters. The article was written by Tanis, Steven P.; Colca, Jerry R.; Parker, Timothy T.; Artman, Gerald D. III; Larsen, Scott D.; Gadwood, Robert C.; Zeller, James R.. The article contains the following contents:

Ketones I [R = H, OMe; R1 = H, Et; Y = C(O); X = CH, N] were selected for clin. development, however their initial syntheses were considered suboptimal for application deep into clin. trials. Direct ketone introduction/maintenance was desired for maximum efficiency and convergence was found to be critically dependent upon the acidity of the nucleophilic species I [R = OMe; R1 = H; X = CH; Y = CHOH] and 1-(5-Ethyl-2-pyridinyl)-ethanone and the use of pre- or post-alkylative oximino-ether/oxime protection. Improvements in overall yield for the syntheses of compound I [R = H; R1 = Et; Y = C(O); X = N] from 20% to 44% and compound I [R = OMe; R1 = H; Y = C(O); X = CH] from 31% to 59% were realized. The results came from multiple reactions, including the reaction of 2,5-Dibromopyridine(cas: 624-28-2Formula: C5H3Br2N)

2,5-Dibromopyridine(cas: 624-28-2) belongs to pyridine. Pyridines, quinolines, and isoquinolines have found a function in almost all aspects of organic chemistry.

Application of 624-28-2In 2022 ,《Effect of the nuclearity on the catalytic performance of a series of Pd(II) complexes in the Suzuki-Miyaura reaction》 appeared in Journal of Catalysis. The author of the article were Kurpik, Gracjan; Walczak, Anna; Gilski, Miroslaw; Harrowfield, Jack; Stefankiewicz, Artur R.. The article conveys some information:

Development of well-defined multivalent systems with densely packed multiple functional groups located within a single mol. structure provides an excellent opportunity to generate catalysts of enhanced activity. A series of mono-, di- and trinuclear Pd(II) complexes based on polyketonate ligands allied with 2,2′-bipyridine was designed, synthesized and fully characterized in both solution and solid state. The mono-, di- and tritopic β-diketonate mols. serve as scaffolds for Pd(II) active sites which, in the two latter cases, are forced into close proximity. Application of the complexes as catalysts in Suzuki-Miyaura cross-coupling as a model reaction revealed significant differences in reaction yields and a trend in reactivity reflecting their nuclearity. In the experimental materials used by the author, we found 2,5-Dibromopyridine(cas: 624-28-2Application of 624-28-2)

《One-Pot Synthesis of a Linear [4]Catenate Using Orthogonal Metal Templation and Ring-Closing Metathesis》 was published in Inorganic Chemistry in 2020. These research results belong to Colley, Nathan D.; Nosiglia, Mark A.; Li, Lei; Amir, Faheem; Chang, Christy; Greene, Angelique F.; Fisher, Jeremy M.; Li, Ruihan; Li, Xuesong; Barnes, Jonathan C.. SDS of cas: 624-28-2 The article mentions the following:

The efficient synthesis of well-defined, linear oligocatenanes possessing multiple mech. bonds remains a formidable challenge in the field of mech. interlocked mols. Here, a one-pot synthetic strategy is described to prepare a linear [4]catenate using orthogonal metal templation between a macrocycle precursor, composed of terpyridine and phenanthroline ligands spaced by flexible glycol linkers, and a closed phenanthroline-based mol. ring. Implementation of two simultaneous ring-closing metathesis reactions after metal complexation resulted in the formation of three mech. bonds. The linear [4]catenate product was isolated in 55% yield as a mixture of topol. diastereomers. The intermediate metal complexes and corresponding interlocked products (with and without metals) were characterized by NMR, mass spectrometry, gel permeation chromatog., and UV-vis absorption spectroscopy. We envision that this general synthetic strategy may pave the way for the synthesis of higher order linear oligocatenates/catenanes with precise mol. weights and four or more interlocking mol. rings.

2,5-Dibromopyridine(cas: 624-28-2) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.Product Details of 624-28-2

Both Pt complexes showed bright emission in solution and solid state, concomitant with charming external-stimuli-responsive emission under mech. grinding, organic solvent vapors and pressure. The change emission color spanned from yellow to near-IR region. Using the Pt complexes as the dopant, solution processable organic light-emitting diodes (OLEDs) were fabricated and a maximum external quantum efficiency of -18% was achieved, which is the highest value among the reported solution-processable OLEDs based on external-stimuli-responsive luminescence.

Based on the doping of the binary tris-pyrazolate-Sm3+ complex [Sm(tba-PMP)3(5-Br-2,2′-bpy)] (1; 5-Br-2,2′-bpy = 5-bromo-2,2′-bipyridine and (Htba-PMP = 1-phenyl-3-methyl-4-(tert-butylacetyl)-5-pyrazolone)) with an efficient orange-light into the PVK (poly(N-vinylcarbazole)) host, the obtained PVK@1 films exhibit the dichromatic color-tuning (white-light to purplish-pink and to pink) characters strictly relative to the Sm3+-doping content and the λex wavelength. Further using the PVK@1 film (10:1; wt/wt) with the straightforward white-light (φPL = 5.8%) as the emitting layer, its single-component solution-processed WPLED gives the electroluminescent performance (LMax of 157 cd/m2, ηMaxc of 0.65 cd/A and the white-light-emitting stability) satisfactory enough for portable full-color flat displays.

《Phenotypic Discovery of an Antivirulence Agent against Vibrio vulnificus via Modulation of Quorum-Sensing Regulator SmcR》 was published in ACS Infectious Diseases in 2020. These research results belong to Kim, Seung Min; Park, Jongmin; Kim, Myun Soo; Song, Heebum; Jo, Ala; Park, Hankum; Kim, Tae Sung; Choi, Sang Ho; Park, Seung Bum. Formula: C5H3Br2N The article mentions the following:

An antivirulence agent against Vibrio vulnificus named quoromycin (QM, I) was discovered by a phenotype-based elastase inhibitor screening. Using the fluorescence difference in two-dimensional gel electrophoresis (FITGE) approach, SmcR, a quorum-sensing master regulator and homolog of LuxR, was identified as the target protein of QM. We confirmed that the direct binding of QM to SmcR inhibits the quorum-sensing signaling pathway by controlling the DNA-binding affinity of SmcR and thus effectively alleviates the virulence of V. vulnificus in vitro and in vivo. I can be regarded as a novel antivirulence agent for the treatment of V. vulnificus infection.
