Spin-labeled (acylated with 4-doxylpentanoic acid) emoxypine, methionine, o-anisidine were synthesized. The compounds obtained were characterized using nuclear magnetic resonance spectroscopy, electron paramagnetic resonance spectroscopy, infrared and ultraviolet spectroscopy and mass spectrometry. Synthesized spin-labeled compounds can be used for biochemical studies using EPR spectroscopy.
