Chemical Structure
Description
Owing to bromine/iodine substitution, an aromatic ring system, 1,3-Dibromo-5-iodo-2-methylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 375.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
1,3-Dibromo-5-iodo-2-methylbenzene (CAS 704909-84-2), molecular formula C7H5Br2I and molecular weight 375.83 g/mol, is a CATO reference standard with documented purity and traceability.
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.
