Application of 3641-13-2, New Advances in Chemical Research in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 3641-13-2, name is 5-Amino-4H-1,2,4-triazole-3-carboxylic acid, molecular formula is C3H4N4O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
General procedure: A mixture of benzil (0.01 mol), aldehydes (0.01 mol), 3-amino-1,2,4-triazole-5-carboxylic acid (0.01 mol), ammonium acetate (0.01 mol) and ceric ammonium nitrate (15 mol%) as a catalyst were refluxed in ethanol (15 mL) for about 3-4 h. The progress of the reaction was monitored by TLC. After completion of reaction, the mixture was cooled to room temperature. The solid formed was filtered and dried. The crude products were recrystallized by ethanol.
By the way, if you are interested in learning more fun chemistry with your kids, get your hands into one chemistry set now, and start enjoying the best part of chemistry: experiments about 5-Amino-4H-1,2,4-triazole-3-carboxylic acid.
