Description

Structurally, 35218-75-8 Tetraphenylporphine sulfonate Benzenesulfonic acid, 4,4',4'',4'''-(21H,23H-porphine-5,10,15,20-tetrayl)tetrakis- 4,4',4'',4'''-(21H,23H-Porphine-5,10,15,20-tetrayl)tetrakis(benzenesulfonic acid) 4,4',4'',4'''-(21H,23H-Porphine-5,10,15,20-tetrayl)tetrakisbenzenesulfonic acid meso-Tetra(p-sulfonatophenyl)porphine meso-Tetra-(4-sulfonatophenyl)porphine TPPS4 TPPS (photoreactant) WR 247188 (C44H76N4O12S4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 981.35 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
