51592-06-4 Iodo-gen 1,3,4,6-Tetrachloro-3 alpha,6 alpha-diphenylglycoluril Glycoluril, 1,3,4,6-tetrachloro-3a,6a-diphenyl- Imidazo(4,5-d)imidazole-2,5(1H,3H)-dione, 1,3,4,6-tetrachlorotetrahydro-3a,6a-diphenyl- 1,3,4,6-Tetrachlorotetrahydro-3a, 6a-diphenylimidazo(4,5-d)imidazole-2,5(1H,3H)-dione 1-26-00-00148 (Beilstein Handbook Reference) BRN 0363328 NSC 4462 1,3,4,6-Tetrachloro-3a,6a-diphenylglycoluril Iodogen (CAS 51592-06-4) is a high-purity analytical reference standard with the molecular formula C16H22Cl4N4O2 and a molecular weight of 444.18 g/mol.
Based on its molecular formula C16H22Cl4N4O2, 51592-06-4 Iodo-gen 1,3,4,6-Tetrachloro-3 alpha,6 alpha-diphenylglycoluril Glycoluril, 1,3,4,6-tetrachloro-3a,6a-diphenyl- Imidazo(4,5-d)imidazole-2,5(1H,3H)-dione, 1,3,4,6-tetrachlorotetrahydro-3a,6a-diphenyl- 1,3,4,6-Tetrachlorotetrahydro-3a, 6a-diphenylimidazo(4,5-d)imidazole-2,5(1H,3H)-dione 1-26-00-00148 (Beilstein Handbook Reference) BRN 0363328 NSC 4462 1,3,4,6-Tetrachloro-3a,6a-diphenylglycoluril Iodogen contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 444.18 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
