553-94-6 Benzene, 2-bromo-1,4-dimethyl- 2-Bromo-p-xylene p-Xylene, 2-bromo- (8CI) 1-Bromo-2,5-dimethylbenzene 2-Bromo-1,4-dimethylbenzene Bromo-p-xylene 2-Bromo-1,4-xylene 2,5-Dimethylbromobenzene 2,5-Dimethylphenyl bromide EINECS 209-055-7 NSC 8051 2,5-Xylyl bromide (C8H15Br) contains 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.

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.
