1. By IR: IR Spectrum of the test exhibits intense peaks at about 3055, 1438 and 1000 cm ^-1 (±5 cm ^-1 ).
2. By GC: The retention time of 2-bromo Iodobenzene peak in the chromatogram of test preparation corresponds to that in the chromatogram of the standard preparation as obtained under purity by GC method.
