Uses

Used in Pharmaceutical Industry:
(1S,2S,3R,5S)-3-(7-(((1R,2S)-2-(3,4-difluorophenyl)cyclopropyl)amino)-5-(propylsulfinyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-3-yl)-5-(2-hydroxyethoxy)cyclopentane-1,2-diol is used as an impurity in the synthesis of ticagrelor, a reversible oral P2Y12 receptor antagonist. Ticagrelor provides faster, greater, and more consistent ADP-receptor inhibition than Clopidogrel, making it an effective treatment for acute coronary syndromes (ACS). The presence of (1S,2S,3R,5S)-3-(7-(((1R,2S)-2-(3,4-difluorophenyl)cyclopropyl)aMino)-5-(propylsulfinyl)-3H-[1,2,3]triazolo[4,5-d]pyriMidin-3-yl)-5-(2-hydroxyethoxy)cyclopentane-1,2-diol as an impurity in ticagrelor may affect the drug's efficacy and safety, and its analysis and control are crucial in ensuring the quality of the final pharmaceutical product.
