4-Chloro-7-methylthieno[3,2-d]pyrimidine (cas: 175137-21-0) belongs to pyrimidine derivatives. Pyrimidine also found in many synthetic compounds such as barbiturates and the HIV drug, zidovudine. As nucleotides in DNA and RNA, pyrimidine nucleotide derivatives have a wide range of biological applications. For example, pyrimidine derivatives are useful in DNA repair studies involving cancer and epigenetics.Recommanded Product: 4-Chloro-7-methylthieno[3,2-d]pyrimidine

The efficient one-step chlorination of methylsulfanyl group on pyrimidine ring system with sulfuryl chloride was written by Ham, Young Jin;Lee, Duck-Hyung;Choi, Hwan Geun;Hah, Jung-Mi;Sim, Taebo. And the article was included in Tetrahedron Letters in 2010.Recommanded Product: 4-Chloro-7-methylthieno[3,2-d]pyrimidine This article mentions the following:

A facile one-step transformation of methylsulfanyl and arylsulfanyl groups on pyrimidine ring system into the corresponding chloride group was achieved using sulfuryl chloride in acetonitrile/dichloromethane. In the experiment, the researchers used many compounds, for example, 4-Chloro-7-methylthieno[3,2-d]pyrimidine (cas: 175137-21-0Recommanded Product: 4-Chloro-7-methylthieno[3,2-d]pyrimidine).
