4-Chloro-5-methylthieno[2,3-d]pyrimidine (CAS 106983-73-3) is a key heterocyclic intermediate in pharmaceutical synthesis. Its molecular formula is C7H5ClN2S. Produced via cyclization of thiophene derivatives with amidines, this compound serves as a critical scaffold for developing kinase inhibitors and antiviral agents.
Store under inert atmosphere at 2-8°C to prevent hydrolysis. Handle with appropriate PPE due to potential mutagenicity. Do not use in uncontrolled clinical settings without rigorous purification validation.
