5-Amino-1-methyl-1H-pyrazole-4-carboxamide (cas: 18213-75-7) belongs to pyrazole derivatives. Pyrazoles, a five-membered heterocycle containing two adjacent nitrogen atoms, are the core structures found in a number of molecules that possess a wide range of pharmaceutical and agricultural activities. Pyrazoles can be selectively lithiated at different carbons and subsequently react with electrophiles depending on the substitution patterns.HPLC of Formula: 18213-75-7

Condensed pyrimidine systems. 5.6-methyl-functionalized in pyrazolo[3,4-d]pyrimidin-4(5H)-ones was written by Bol’but, A. V.;Vovk, M. V.. And the article was included in Zhurnal Organichnoi ta Farmatsevtichnoi Khimii in 2006.HPLC of Formula: 18213-75-7 This article mentions the following:

The cyclocondensation of chloroacetyl chloride with 5-amino-1H-pyrazole-4-carboxamide derivatives gave 6-(chloromethyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one derivatives Reaction of the latter with thiourea or sodium azide gave 6-[[amino(imino)thio]methyl]-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one and 6-(azidomethyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one derivatives The latter compounds were then converted into corresponding 6-(aminomethyl), 6-(amidomethyl)- and 6-(thiomethyl) derivatives In the experiment, the researchers used many compounds, for example, 5-Amino-1-methyl-1H-pyrazole-4-carboxamide (cas: 18213-75-7HPLC of Formula: 18213-75-7).
