Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 288.34 g/mol gives 1,4-Dibromo-2-chloro-3-fluorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,4-Dibromo-2-chloro-3-fluorobenzene (CAS 1000573-09-0) is a high-purity analytical reference standard with the molecular formula C6H2Br2ClF and a molecular weight of 288.34 g/mol.
Structurally, 1,4-Dibromo-2-chloro-3-fluorobenzene (C6H2Br2ClF) contains fluorine/chlorine/bromine 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 288.34 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
