Chemical Structure
Description
Structurally, 627-31-6 1,3-Diiodopropane Propane, 1,3-diiodo- 4-01-00-00228 (Beilstein Handbook Reference) AI3-52340 BRN 1731117 EINECS 210-993-4 NSC 35647 Trimethylene diiodide (C3H6I2) contains iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 295.89 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
