Hazard Class IRRITANT
2,4-Dichloro-7H-Pyrrolo[2,3-d]pyrimidine (2,6-Dichloro-7-Deazapurine) (CAS: 90213-66-4) is used as a pharmaceutical intermediate, intermediate of Tofacitinib Citrate (CAS: 540737-29-9). Tofacitinib Citrate is an oral drug used for treating rheumatoid arthritis. Tofacitinib Citrate belongs to a class of drugs called Janus kinase (JAK) inhibitors. JAKs are enzymes (proteins) that regulate chemical signaling pathways that control biologic processes such as blood formation and the immune response that causes the pain, tenderness and swelling of inflammation. JAKs are found in many cells, especially stem cells in bones and joints. Inhibition of JAKs by tofacitinib prevents inflammation and tissue destruction that is associated with the inflammation of rheumatoid arthritis.
