3-Bromo-4'-isopropyl-1,1'-biphenyl CAS 1443306-16-8

Description

The occurrence of 3-Bromo-4'-isopropyl-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.

3-Bromo-4'-isopropyl-1,1'-biphenyl (CAS 1443306-16-8), molecular formula C15H15Br and molecular weight 275.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H15Br, 3-Bromo-4'-isopropyl-1,1'-biphenyl contains bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 275.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.
