Shanghai Ruifu Chemical Co., Ltd. is the leading manufacturer and supplier of 3,6-Dichloropyrazine-2-Carbonitrile (CAS: 356783-16-9) with high quality. It is an intermediate typically in the synthesis of 6-Fluoro-3-Hydroxypyrazine-2-Carboxamide commercially named Favipiravir (CAS: 259793-96-9). Favipiravir (CAS: 259793-96-9) in the treatment of Influenza virus infections. Favipiravir is a broad-spectrum antiviral drug that was cleared by the Drugs Controller General of India (DCGI) last week for “emergency restricted” use among Covid-19 patients. Glenmark will sell the generic favipiravir under the brand name FabiFlu. Favipiravir was originally developed in the late 1990s by a company that was later purchased by the Japanese firm Fujifilm as part of its transition from the photo business to healthcare. After being tested against a range of viruses, the drug was approved in Japan in 2014 for emergency use against flu epidemics or to treat new strains of influenza.
