Abstract: After the synthesis and isolation of methylated bismuth cysteine, its initial identification by IR-spectroscopy was performed, whereas for definitive identification, high resolution mass spectrometry (ESI-TOF-MS and LTQ Orbitrap) was carried out.

Keywords: high resolution mass spectrometry - methyl bismuth cysteine - IR - synthesis
