Among various organic chelating agents thiosemicarbazones occupy an important role due to their efficiency towards many metal ions through thionate sulphur atom and hydrazino nitrogen atom. Thiosemicarbazones can be obtained by condensing thiosemicarbazide with various carbonyl compounds. In recent years, the usage of thiosemicarbazone ligands has been reported by so many authors in the fields of analytical and biological. The present study reported about of two newly synthesized thiosemicarbazone ligands, namely 2,3,4-trihydroxybenzaldehyde-4-phenylthiosemicarbazone (THBPTSC) and 2,3,4-trihydroxybenzaldehyde-4-methylthiosemi carbazone (THBMTSC). These two new ligands are characterized with various spectral techniques, such as FT-IR, NMR and mass spectral techniques. The elemental composition was checked with elemental analysis report. Molar conductivity measurements of the ligands also reported.
