Chemical Structure
Description
The occurrence of 3-bromo-5-(bromomethyl)benzonitrile is closely related to a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-bromo-5-(bromomethyl)benzonitrile (CAS 124289-24-3) is a high-purity analytical reference standard with the molecular formula C8H11Br2N and a molecular weight of 280.99 g/mol.
3-bromo-5-(bromomethyl)benzonitrile (C8H11Br2N) contains a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
