Abstract
High performance liquid chromatographic and TLC densitometric assay methods for 2,2'-dicarbomethoxy amino 5,5'- dibenzimidazolyl ketone (C.D.R.I.Code No. 82/437) a new antifilarial compound, are described. The sensitivity of the HPLC method was found to be 0.5 mcg/ml, and that of the TLC densitometric method 0.5 mcg.
