Chemical Structure

5-Bromo-1,3-difluoro-2-iodobenzene CAS 160976-02-3 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.

5-Bromo-1,3-difluoro-2-iodobenzene (CAS 160976-02-3) is a high-purity analytical reference standard with the molecular formula C6H2BrF2I and a molecular weight of 318.89 g/mol.

5-Bromo-1,3-difluoro-2-iodobenzene (C6H2BrF2I) contains fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
