Chemical Structure

3,5-DIbromo-2-fluorotoluene CAS 85233-13-2 chemical structure

Description

3,5-DIbromo-2-fluorotoluene (C7H5Br2F) contains fluorine/bromine 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).

3,5-DIbromo-2-fluorotoluene (CAS 85233-13-2) is a high-purity analytical reference standard with the molecular formula C7H5Br2F and a molecular weight of 267.92 g/mol.

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.
