Application of 16681-70-2, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid, This compound has unique chemical properties. The synthetic route is as follows.
To a stirred solution of 2S,45)-4-amino-5-biphenyl-4-yl-2-(2- hydroxyethoxymethyl)pentanoic acid ethyl ester (17 mg, 47 muiotaetaomicron) in DMF (0.3 mL), was added lH-l,2,3-triazole-4-carboxylic acid (5.3 mg, 47 muiotaetaomicron) and HATU (18 mg, 47 muetaiotaomicron), followed by DIPEA (25 mu^, 141 muetaiotaomicron). The mixture was stirred for 30 minutes, then concentrated under reduced pressure to yield crude Compound 1, which was used in the next step without purification.
The chemical industry reduces the impact on the environment during synthesis 1H-[1,2,3]Triazole-4-carboxylic acid. I believe this compound will play a more active role in future production and life.
