Chemical Structure
Description
The occurrence of 4-Iodo-isothiazole is closely related to a nitrile group, sulfur-containing functionality, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Iodo-isothiazole (CAS 49602-28-0) is a high-purity analytical reference standard with the molecular formula C3H2INS and a molecular weight of 211.02 g/mol.
Based on its molecular formula C3H2INS, 4-Iodo-isothiazole contains a nitrile group, sulfur-containing functionality, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 211.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
