A Liquid chromatographic (LC) method using mass spectrometric (MS) detection was developed and validated for the trace analysis (ppm level) of 4-Bromo methyl-2'-Cyanobiphenyl in Valsartan drug substances. LC analysis of 4-Bromo methyl-2'-Cyanobiphenyl was done on Necleosil C18 (100 mm x 4.6 mm, 3 µm) column and the mobile phase is in the ratio of 50:50:1 containing water, acetonitrile, and acetic acid. The flow rate was 1.0 mL min-1 and the elution was monitored at 225 nm. The method was validated as per International Conference on Harmonization (ICH) guidelines. LC-MS is able to quantitate up to 1.0 ppm of 4-Bromo methyl-2'-cyanobiphenyl.
