Chemical Structure
Description
The occurrence of 1-Bromo-3,5-dichloro-2-iodobenzene is closely related to chlorine/bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-3,5-dichloro-2-iodobenzene (CAS 81067-44-9), molecular formula C6H2BrCl2I and molecular weight 351.79 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Bromo-3,5-dichloro-2-iodobenzene (C6H2BrCl2I) contains chlorine/bromine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 351.79 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), 1-Bromo-3,5-dichloro-2-iodobenzene 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.
