Pyrazole and its derivatives are considered a pharmacologically important active scaffold that possesses almost all types of pharmacological activities. 37622-90-5, formula is C6H8N2O2, Name is Ethyl 4-pyrazolecarboxylate. Pyrazole is a weak base, with pKb 11.5 (pKa of the conjugated acid 2.49 at 25 \u00b0C).Pyrazole used as a ligand to prepare organometallic compounds. Formula: C6H8N2O2<\/a>.<\/p>\n

Iskauskiene, Monika;Ragaite, Greta;Sloek, Frank A.;Sackus, Algirdas research published \u300a Facile synthesis of novel amino acid-like building blocks by N-alkylation of heterocyclic carboxylates with N-Boc-3-iodoazetidine\u300b, the research content is summarized as follows. An efficient protocol providing easy access to highly functionalized heterocyclic compounds as novel organic building blocks was developed by coupling alkyl pyrazole-, indazole- and indolecarboxylates with N-Boc-3-iodoazetidine. The synthesized compounds were representatives of constrained non-chiral synthetic azole carboxylates in their N-Boc protected ester forms. Diversification of the prepared heterocyclic building blocks was achieved via application of palladium-catalyzed Suzuki-Miyaura cross-coupling reactions. In total, 34 building blocks were obtained to form a highly diversified small mol. collection. The structure of the novel heterocyclic compounds was investigated and verified by advanced NMR spectroscopy methods.<\/p>\n

37622-90-5, 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, Formula: C6H8N2O2<\/a><\/p>\n
