On September 5, 2012, Akiri, Kalyanachakravarthi; Cherukuvada, Suryanarayan; Rana, Soumendra; Nangia, Ashwini published an article.Related Products of 636-73-7 The title of the article was Crystal Structures of Pyridine Sulfonamides and Sulfonic Acids. And the article contained the following:

Despite the widespread occurrence of pyridinesulfonic acid and pyridinesulfonamide functional groups in drugs and pharmaceuticals, and their use as ligands in metal-organic frameworks, a systematic structural study of their H bonding and mol. packing is lacking. Crystal structures of 2-, 3-, and 4-pyridinesulfonic acids/amides in terms of N+-H···O- H bonds, N-H···O dimer/catemer synthons, and graph set notations are discussed. This model study provides a background for polymorph screening and solid form hunting of pharmacol. active sulfonamides. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Related Products of 636-73-7

On August 31, 2010, Nirmalram, Jeyaraman Selvaraj; Muthiah, Packianathan Thomas published an article.Formula: C5H5NO3S The title of the article was Hydrogen-bonding patterns in pyrimethaminium pyridine-3-sulfonate. And the article contained the following:

In the asym. unit of the title salt [systematic name: 2,4-diamino-5-(4-chlorophenyl)-6-ethylpyrimidin-1-ium pyridine-3-sulfonate], C12H14N4Cl+·C5H4NSO3-, there are two independent pyrimethaminium cations and two 3-pyridine sulfonate anions. Each sulfonate group interacts with the corresponding protonated pyrimidine ring through two N-H…O hydrogen bonds, forming a cyclic hydrogen-bonded bimol. R22(8) motif. Even though the primary mode of association is the same, the next higher level of supramol. architectures are different due to different hydrogen-bonded networks. In one of the independent mols. in the asym. unit, the pyrimethamine cation is paired centrosym. through N-H…N hydrogen bonds, generating an R22(8) ring motif. In the other mol., the pyrimethamine cation does not form any base pairs; instead it forms hydrogen bonds with the 3-pyridine sulfonate anion. The structure is further stabilized by C-H…O, C-H…N and π-π stacking [centroid-centroid distance = 3.9465 (13) Å] interactions. Crystallog. data are given. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Formula: C5H5NO3S

On December 3, 2001, Makinen, Silja K.; Melcer, Natalia J.; Parvez, Masood; Shimizu, George K. H. published an article.SDS of cas: 636-73-7 The title of the article was Highly selective guest uptake in a silver sulfonate network imparted by a tetragonal to triclinic shift in the solid state. And the article contained the following:

The Ag sulfonate network presented herein, Ag 3-pyridinesulfonate, reversibly and selectively absorbs MeCN while undergoing a major structural rearrangement. The origin of this structural flexibility is a coupling of the weak coordinating ability of the SO3 group with the geometrically pliant Ag(I) center. Single crystal and powder x-ray structures of both the desolvated and solvated forms are presented in addition to the mechanism of their reversible interconversion. A heterogeneous gas chromatog. study showing selective extraction of the MeCN is also presented. Extended solid frameworks which reorder to any extent are not common but the structure presented herein transforms from a tetragonal to a triclinic crystal system. The results indicate that cooperative interactions in systems based on supposedly weaker interactions can yield softer yet functional networks with behavior unlike that observed in more rigid inorganic frameworks.

Yang, Bing; Jiang, Xin; Guo, Qing; Lei, Tao; Zhang, Li-Ping; Chen, Bin; Tung, Chen-Ho; Wu, Li-Zhu published an article in 2016, the title of the article was Self-Assembled Amphiphilic Water Oxidation Catalysts: Control of O-O Bond Formation Pathways by Different Aggregation Patterns.Formula: C5H5NO3S And the article contains the following content:

The oxidation of water to mol. oxygen is the key step to realize water splitting from both biol. and chem. perspective. In an effort to understand how water oxidation occurs on a mol. level, a large number of mol. catalysts have been synthesized to find an easy access to higher oxidation states as well as their capacity to make O-O bond. However, most of them function in a mixture of organic solvent and water and the O-O bond formation pathway is still a subject of intense debate. Herein, we design the first amphiphilic Ru-bda (H2bda=2,2′-bipyridine-6,6′-dicarboxylic acid) water oxidation catalysts (WOCs) of formula [RuII(bda)(4-OTEG-pyridine)2] (1, OTEG=OCH2CH2OCH2CH2OCH3) and [RuII(bda)(PySO3Na)2] (2, PySO3-=pyridine-3-sulfonate), which possess good solubility in water. Dynamic light scattering (DLS), scanning electron microscope (SEM), critical aggregation concentration (CAC) experiments and product anal. demonstrate that they enable to self-assemble in water and form the O-O bond through different routes even though they have the same bda2- backbone. This work illustrates for the first time that the O-O bond formation pathway can be regulated by the interaction of ancillary ligands at supramol. level. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Formula: C5H5NO3S

On January 20, 1989, Corey, E. J.; Posner, Gary H.; Atkinson, Richard F.; Wingard, Astrid K.; Halloran, Daniel J.; Radzik, Donna M.; Nash, John J. published an article.Safety of Pyridine-3-sulfonic acid The title of the article was Formation of olefins via pyrolysis of sulfonate esters. And the article contained the following:

Esters, e.g., I and II, of 8-quinolinesulfonic acid and 2-pyridinesulfonic acid were synthesized from alcs. and the acid chlorides. The secondary esters decomposed cleanly at moderate temperatures to give olefins in high yields. Thus, I was heated at 150° to give 92% cyclohexene. Product studies were consistent with carbocation formation and abstraction by a ring nitrogen to give the olefin. The importance of a basic group was confirmed by pyrolysis of a series of para-substituted cyclohexyl benzenesulfonates III (R = NHAc, NHEt, NO2, Br, Me, MeO, Me2N). Thermolysis of III (R = NHEt, NHAc) cleanly gave cyclohexene in good yield; however, thermolysis of III (R = NO2, Br, Me Me) gave cyclohexene in low yield along with considerable amounts of tar. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Safety of Pyridine-3-sulfonic acid
