Chemical Structure
Description
The occurrence of 3'-Bromo-3,4-dimethyl-1,1'-biphenyl is closely related to bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3'-Bromo-3,4-dimethyl-1,1'-biphenyl (CAS 89346-63-4), a certified reference material (molecular formula C14H13Br, MW 261.16 g/mol) for analytical method development and quality control.
Owing to bromine substitution, a polycyclic aromatic system, 3'-Bromo-3,4-dimethyl-1,1'-biphenyl is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 261.16 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.
