Pyrazoles and pyrimidines have diverse biological and pharmacological activities. 37622-90-5, formula is C6H8N2O2, Name is Ethyl 4-pyrazolecarboxylate. There are a number of antimicrobial compounds containing pyrazole moiety as the core unit. Application In Synthesis of 37622-90-5<\/a>.<\/p>\n

Sheridan, Thomas;Yayla, Hatice G.;Lian, Yajing;Genovino, Julien;Monck, Nat;Burton, Jonathan W. research published \u300a Organophotochemical SN<\/sub>Ar Reactions of Mildly Electron-Poor Fluoroarenes\u300b, the research content is summarized as follows. C-F functionalization of arenes with a range of alc. and pyrazole nucleophiles has been achieved without the need for metal catalysts or highly electron-poor substrates. Treatment of fluoroarenes with alcs. or pyrazoles and DDQ under irradiation by blue LED light provides the corresponding substituted products. The procedure is complementary to classical SN<\/sub>Ar chem. which generally requires basic reaction conditions and high temperatures, and provides products under non-basic conditions at \u2248 40\u00b0C.<\/p>\n

Application In Synthesis of 37622-90-5<\/a>, Ethyl 4-pyrazolecarboxylate, also known as Ethyl pyrazole-4-carboxylate, is a useful research compound. Its molecular formula is C6H8N2O2 and its molecular weight is 140.14 g\/mol. The purity is usually 95%.<\/p>\n

Ethyl pyrazole-4-carboxylate is a low yield, transition metal salt that is used in the synthesis of pyrazoles. It can be synthesized by the reaction of sodium ethoxide with ethyl chloroformate and a Grignard reagent. Sodium ethoxide is added to a suspension of sodium chloride and dried ethyl chloroformate, followed by addition of magnesium turnings. The mixture is refluxed for one hour, cooled, and filtered to give crystals. Ethyl pyrazole-4-carboxylate is used in the preparation of ethyl esters from aliphatic alcohols by reacting with boron trichloride or phosphorus pentachloride. It participates in certain chemical reactions as a byproduct and can damage equipment during chemical reactions. The yield of this compound can be increased by using an excess amount of Grignard reagent or adding hexamethylenetetramine to the reaction mixture, 37622-90-5.<\/p>\n
