Chemical Structure
Description
The occurrence of 1,3-Dibromo-2-iodo-4,5-dimethylbenzene is closely related to bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Dibromo-2-iodo-4,5-dimethylbenzene (CAS 1160573-39-6) is a high-purity analytical reference standard with the molecular formula C8H7Br2I and a molecular weight of 389.85 g/mol.
Structurally, 1,3-Dibromo-2-iodo-4,5-dimethylbenzene (C8H7Br2I) contains 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 389.85 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
