COA of Formula: C2H4N4. I found the field of Chemistry very interesting. Saw the article Efficient Synthesis and Antimicrobial Evaluation of New Azolopyrimidines-Bearing Pyrazole Moiety published in 2019.0, Reprint Addresses Gomha, SM (corresponding author), Cairo Univ, Fac Sci, Dept Chem, Giza, Egypt.; Gomha, SM (corresponding author), Islamic Univ Almadinah Almonawara, Fac Sci, Dept Chem, Almadinah Almonawara 42351, Saudi Arabia.. The CAS is 61-82-5. Through research, I have a further understanding and discovery of 1H-1,2,4-Triazol-5-amine.
Sodium salt of 3-hydroxy-1-(1-aryl-5-methylpyrazolyl)propenone derivatives was used as a precursor for synthesis of various fused azolopyrimidine ring systems as pyrazolopyrimidines, triazolopyrimidines, and pyrimidobenzimidazoles following many procedures. The identity of the prepared compounds was elucidated by their spectral data and elemental analyses. The in vitro antimicrobial activity of 13 new compounds was evaluated, and many derivatives showed good to moderate activity.
COA of Formula: C2H4N4. About 1H-1,2,4-Triazol-5-amine, If you have any questions, you can contact Abdelhamid, AO; Gomha, SM; El-Enany, WAMA or concate me.
