Chemical Structure
Description
The occurrence of Dibenzo[b,d]iodol-5-ium iodide is closely related to iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dibenzo[b,d]iodol-5-ium iodide (CAS 1010-76-0) is a high-purity analytical reference standard with the molecular formula C12H8IHI and a molecular weight of 407.00 g/mol.
The molecular framework of Dibenzo[b,d]iodol-5-ium iodide (C12H8IHI) is characterized by iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), Dibenzo[b,d]iodol-5-ium iodide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
