What is TCPP (Tetrakis(4-carboxyphenyl)porphyrin Ultra-high sensitive spectrophotometric reagent for Cu, Cd For the simultaneous determination of metals by HPLC)?

TCPP (Tetrakis(4-carboxyphenyl)porphyrin Ultra-high sensitive spectrophotometric reagent for Cu, Cd For the simultaneous determination of metals by HPLC)
CAS:14609-54-2
Molecular Formula:C48H30N4O8
Molecular Weight: 790.77g/mol
Description
The purity is not less than 97.0%(LC)(T). Its grade is Ace. Its specification is 100mg or 1g.
In neutral and alkaline solutions, tetrakis(4-carboxyphenyl)porphyrin (TCPP) and tetrakis(4-sulfonatophenyl)porphyrin (TSPP) form 1:1 and 2:1 host–guest inclusion complexes with agr-cyclodextrin (agr-CD), beta-cyclodextrin (beta-CD), and 6-deoxy-6-diethylamino-beta-CD (DEA-beta-CD), except for DEA-beta-CD in alkaline solution. On the other hand, TCPP and TSPP form only 1:1 inclusion complexes with 6-deoxy-6-dihexylamino-beta-CD (DHA-beta-CD). The limited solubilities of DEA-beta-CD in alkaline solution and DHA-beta-CD are likely responsible for no observation of the 2:1 inclusion complex containing DEA-beta-CD in alkaline solution and that containing DHA-beta-CD. The equilibrium constants (Ks) of TCPP and TSPP for the formation of the inclusion complexes have been estimated from the absorption and/or fluorescence intensity changes in neutral and alkaline solutions.
