FAQ:

Application:

6-Chloro-2-methyl-2H-indazol-5-amine (CAS: 1893125-36-4) is an intermediate of Ensitrelvir (S-217622). Ensitrelvir by Shionogi & Co. is a highly effective antiviral drug that works just as well as Pfizer's Paxlovid. Oral Xocova (Ensitrelvir), which has the same mechanism of action as Pfizer’s Paxlovid (Nirmatrelvir+Ritonavir), differs in that it only needs to be taken once a day, while the therapeutic effectiveness of ensitrelvir does not seem to be inferior to Paxlovid. As a reminder, Nirmatrelvir is administered twice daily, together with the booster represented by Ritonavir. Ensitrelvir became the first Japanese domestic pill to treat COVID-19, third to be regulatorally approved in Japan; in February 2022.
