Description
576-83-0 Benzene, 2-bromo-1,3,5-trimethyl- 2-Bromomesitylene Mesitylene, 2-bromo- (8CI) AI3-07033 Bromomesitylene 1-Bromo-2,4,6-trimethylbenzene EINECS 209-405-9 Mesityl bromide NSC 8064 2,4,6-Trimethylbromobenzene 2,4,6-Trimethylphenyl bromide (CAS 576-83-0), molecular formula C9H17Br and molecular weight 205.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 576-83-0 Benzene, 2-bromo-1,3,5-trimethyl- 2-Bromomesitylene Mesitylene, 2-bromo- (8CI) AI3-07033 Bromomesitylene 1-Bromo-2,4,6-trimethylbenzene EINECS 209-405-9 Mesityl bromide NSC 8064 2,4,6-Trimethylbromobenzene 2,4,6-Trimethylphenyl bromide (C9H17Br) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
