1,4-Dibromo-2-chloro-1,1,2-trifluorobutane CAS 378-13-2

Description

The occurrence of 1,4-Dibromo-2-chloro-1,1,2-trifluorobutane is closely related to fluorine/chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,4-Dibromo-2-chloro-1,1,2-trifluorobutane (CAS 378-13-2) is a high-purity analytical reference standard with the molecular formula C4H4Br2ClF3 and a molecular weight of 304.33 g/mol.

Based on its molecular formula C4H4Br2ClF3, 1,4-Dibromo-2-chloro-1,1,2-trifluorobutane contains fluorine/chlorine/bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 304.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
