Chemical Structure
Description
The occurrence of 4-Iodothieno[3,2-d]pyrimidine is closely related to a nitrile group, sulfur-containing functionality, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Iodothieno[3,2-d]pyrimidine (CAS 1593776-54-5) is a high-purity analytical reference standard with the molecular formula C6H3IN2S and a molecular weight of 262.07 g/mol.
The molecular framework of 4-Iodothieno[3,2-d]pyrimidine (C6H3IN2S) is characterized by a nitrile group, sulfur-containing functionality, iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
