Chemical Structure
Description
4-Bromo-4'-vinyl-1,1'-biphenyl (CAS 4130-13-6), molecular formula C14H11Br and molecular weight 259.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Bromo-4'-vinyl-1,1'-biphenyl (C14H11Br) contains bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 259.14 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
