The electrospray ionization tandem mass spectrometry of 3 tetraphenylporphyrin derivatives containing hydroxyl group (HPTPP) was studied. The proposed fragmentation pathways were summarized. The fragments with the loss of active hydroxyl group or hydroxylphenyl group were observed only in the fragmentation pathway of HPTPP and the fragmentation of the porphyrin with electron – withdrawing substituents at Ph group was easier than that of the porphyrin electron – donating substituents at Ph group. It seemed that the substituents at Ph group in porphyrin had some effects on their fragmentation. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Electric Literature of C47H36N4O).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Attachment of the ligand to the metal may be through a single atom, in which case it is called a monodentate ligand, or through two or more atoms, in which case it is called a didentate or polydentate ligand. Precious metals and metal oxides on carrier materials are used in many industrial processes as heterogenous catalysts.Electric Literature of C47H36N4O
