Pyrolysis of SPhMDPOBn adsorbed on the silica surface (0.6 mmol g−1). (A) Mass spectrum of pyrolysis products at 105°C, obtained after electron impact ionization. (B) Mass spectrum of pyrolysis products at 175°C, obtained after electron impact ionization. (C) Thermograms for m/z 125, 110, 109, 108, 97, 91, 82, 84, 79, 77, and 66 under pyrolysis of О-(phenyl-2-acetamido-2,3-dideoxy-1-thio-β-d-glucopyranoside-3-yl)-d-lactoyl-l-alanyl-d-isoglutamine (SPhMDPOBn) adsorbed on the silica surface.
