2,5-Dibromobenzotrifluoride 1,4-dibromo-2-(trifluoromethyl)benzene 1,4-Dibromo-2-trifluoromethyl-benzene 2,5-Dibromo-A,A,A-trifluorotoluene 7657-09-2 CAS 7657-09-2

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.

2,5-Dibromobenzotrifluoride 1,4-dibromo-2-(trifluoromethyl)benzene 1,4-Dibromo-2-trifluoromethyl-benzene 2,5-Dibromo-A,A,A-trifluorotoluene 7657-09-2 (CAS 7657-09-2) is a high-purity analytical reference standard with the molecular formula C7H9Br2F3 and a molecular weight of 309.95 g/mol.

2,5-Dibromobenzotrifluoride 1,4-dibromo-2-(trifluoromethyl)benzene 1,4-Dibromo-2-trifluoromethyl-benzene 2,5-Dibromo-A,A,A-trifluorotoluene 7657-09-2 (C7H9Br2F3) contains fluorine/bromine substitution. 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.
