Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 289.21 g/mol gives 3-Bromo-4'-(tert-butyl)-1,1'-biphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-4'-(tert-butyl)-1,1'-biphenyl (CAS 1443351-07-2) is a high-purity analytical reference standard with the molecular formula C16H17Br and a molecular weight of 289.21 g/mol.
Owing to bromine substitution, a polycyclic aromatic system, 3-Bromo-4'-(tert-butyl)-1,1'-biphenyl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
