Chemical Structure

3-Bromoiodobenzene CAS 591-18-4 chemical structure

Description

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.

3-Bromoiodobenzene (CAS 591-18-4), molecular formula C6H4BrI and molecular weight 282.90 g/mol, is a CATO reference standard with documented purity and traceability.

3-Bromoiodobenzene (C6H4BrI) contains bromine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 3-Bromoiodobenzene 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.
