Supplementary Fig. 5: LC-ESI-MS of TEMPO-HOCbl.

LC-ESI-MS data for the major peak from the RP-HPLC of the crude product (as highlighted in Supplementary Fig. 3). The peaks between m/z 1500-1600 are close to the molecular mass of TEMPO-HOCbl (1543.61 g/mol) and the peak at m/z 763.55 is close to the half of the molecular mass.
