Cremlyn, Richard J.; Jones, Graham P.; Swinbourne, Fred J.; Yung, Kin published an article in 1980, the title of the article was Some reactions of pyridine-3-sulfonyl chloride.Reference of Pyridine-3-sulfonic acid And the article contains the following content:

Reaction of pyridine-3-sulfonyl chloride-HCl (I) with hydrazine gave the hydrazide from which a semicarbazide and a series of hydrazones were obtained. The chem. shifts of the NH protons of the hydrazones were correlated with the Hammett σ-constants of the substituents. With NaN3 I gave the azide which reacted with both norbornene and Ph3P. I was hydrolyzed to the sulfonic acid by boiling with EtOH. Reaction of the hydrazide with β-diketones afforded the pyrazoles, e.g. II. The intermediate sulfonohydrazones were isolated in each case; however, the product with Et acetoacetate could not be cyclised to the pyrazole. The mass spectra of the pyrazoles are briefly discussed. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Reference of Pyridine-3-sulfonic acid

On September 20, 2019, Yu, Miao; Strotman, Neil A.; Savage, Scott A.; Leung, Simon; Ramirez, Antonio published an article.Reference of Pyridine-3-sulfonic acid The title of the article was A Practical and Robust Multistep Continuous Process for Manufacturing 5-Bromo-N-(tert-butyl)pyridine-3-sulfonamide. And the article contained the following:

A multistep continuous flow process involving (1) magnesium-halogen exchange, (2) sulfonylation with sulfuryl chloride, and (3) reaction with tert-butylamine was developed for the synthesis of an arylsulfonamide pharmaceutical intermediate in the synthesis of BMS-919373. The process was successfully implemented, including a robust control strategy to manage the levels of several process impurities, to produce 76 kg of 5-bromo-N-(tert-butyl)pyridine-3-sulfonamide (I). As the instability of the reactive intermediates and existence of strong exotherms made a batch process unsuitable for production beyond a 1 kg scale, the alternative continuous process led to a practical and robust manufacturing route to the active pharmaceutical ingredient. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Reference of Pyridine-3-sulfonic acid

On October 31, 2014, Zhao, Chongjian; Li, Chuwen; Shen, Moyuan; Huang, Lanfen; Li, Qianhong; Hu, Mingyuan; Deng, Hong published an article.Electric Literature of 636-73-7 The title of the article was Syntheses, structures and photoluminescence of Cd(II) coordination polymers based on in situ synthesized bifunctional ligands. And the article contained the following:

By employing Cd(II) salt, NaN3, and CN-(CH2)n-NC (n = 1, 2) and with the absence or presence of secondary ligands, four new cadmium coordination frameworks, named, {[Cd4(btm)4(H2O)2]·3H2O}n (1); [Cd2(btm)2(H2O)]n (2); [Cd2(bte)(PMA)0.5(H2O)]n (3); and [Cd(tzp)(2,2′-bipy)]n (4) (H2btm = bis(tetrazole) methane: H2bte = 1,2-bis(tetrazole-5-yl)ethane; H2tzp = 1H-tetrazolate-5-propionic acid; bipy = bipyridine; PMA = 1,2,4,5-benzenetetracarboxylic acid) were synthesized via in situ hydrothermal reaction. Single crystal x-ray diffraction reveals that compounds 1-3 are all three-dimensional (3D) frameworks. Compound 1 is constructed by Cd1- and Cd3-btm2- layers and large bridging metalloligands. Compound 2 exhibits a 3D framework with two-dimensional (2D) Cd-btm2- (adopting μ6:κN1, N1′: κN2: κN3: κN4: κN3′: κN4’coordination mode) layers pillared by μ3:κN1, N1′: κN2: κN4′ btm2-. Compound 3 is built up by the Cd-bte2- layers and the linker PMA, with left- and right-handed helical chains arranged alternately. It is notable that btm2- takes on six different coordination modes in 1 and 2. Compound 4 represents a 2D layered framework, which can be simplified into a Shubnikov plane net (4.82̂) topol. network with 3-connected T shape linker tzp2- ligands. In addition, the research results show that compounds 1-4 exhibit different fluorescent behaviors and thermal stabilities. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Electric Literature of 636-73-7

On July 25, 1994, Hurh, Byungserk; Tamane, Tsuneo; Nagasawa, Toru published an article.Product Details of 636-73-7 The title of the article was Purification and characterization of nicotinic acid dehydrogenase from Pseudomonas fluorescens TN5. And the article contained the following:

Membrane-bound nicotinic acid dehydrogenase, an enzyme that catalyzes the formation of 6-hydroxynicotinic acid from nicotinic acid, was solubilized with Triton X-100, and then purified 126-fold with an 11.1% overall recovery from nicotinic acid-induced cells of Pseudomonas fluorescens TN5. The purified enzyme appeared to be homogeneous from anal. by polyacrylamide gel electrophoresis. The enzyme had a mol. mass of approx. 80 kDa and consisted of one subunit. Some electron acceptors, such as phenazine methosulfate, K3Fe(CN)6 and nitro blue tetrazolium, acted as electron acceptors. The purified enzyme catalyzed the hydroxylation of nicotinic acid to 6-hydroxynicotinic acid at a rate of 672 μmol min-1 mg-1 of protein at 35°. It also catalyzed the hydroxylation of pyrazinecarboxylic acid, 3-pyridinesulfonic acid, and 3-cyanopyridine. The purified enzyme exhibited an optimum pH of 8.3, and was sensitive to thiol reagents such as HgCl2 and p-chloromercuribenzoate. A reduction in the amount of the cytochrome c-like component in the respiratory particles was observed during the hydroxylation reaction of nicotinic acid. Thus, nicotinic acid dehydrogenase appeared to be linked to the cytochrome respiratory chain in the cells of P. fluorescens TN5. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Product Details of 636-73-7
