Zinc tetraphenyl-2,3,7,8,12,13,17,18-octamethylporphyrin, also known as Zn(TPOMP), is a chemical compound consisting of a zinc ion (Zn) coordinated to a porphyrin macrocycle. The porphyrin ring is modified with four phenyl groups and eight methyl groups, which are strategically placed to enhance the stability and solubility of the complex. This specific arrangement of substituents on the porphyrin ring influences its electronic properties and reactivity. Zn(TPOMP) is of interest in various fields, including coordination chemistry, materials science, and bioinorganic chemistry, due to its potential applications in catalysis, solar energy conversion, and as a model for understanding the active sites of metalloenzymes. The compound's unique structure allows for the investigation of metal-ligand interactions and the study of its electronic and optical properties, which can be tailored for specific applications.

Check Digit Verification of cas no

The CAS Registry Mumber 28309-93-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,3,0 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28309-93:
(7*2)+(6*8)+(5*3)+(4*0)+(3*9)+(2*9)+(1*3)=125
125 % 10 = 5
So 28309-93-5 is a valid CAS Registry Number.

Spectral, Acid, and Coordination Properties of Dodecasubstituted Porphyrins

Pukhovskaya,Ivanova, Yu. B.,Nam, Dao The,Semeikin,Syrbu,Mamardashvili, N. Zh.

, p. 586 - 596 (2019)

The results of investigation of the interrelation between the geometric structure and coordination, acid, and spectral properties of a series of porphyrins with different systems of meso and β substituents are presented. The geometry of polysubstituted porphyrins was optimized at the DFT B3LYP/6-311G level of theory using Gaussian 09. It was shown that the dianionic forms of dodecasubstituted porphyrins hold promise for the development of highly efficient liquid sensors for metal cations.

Enthalpy—entropy compensation upon metal ion coordination with porphyrins: generalization for the free bases and doubly deprotonated macrocycles

Ivanova, Yu. B.,Koifman, O. I.,Kruk, M. M.,Pukhovskaya, S. G.

, p. 1072 - 1075 (2020/07/25)

Enthalpy—entropy compensation upon the coordination of zinc ions by porphyrins with various structural organizations of peripheral substitution in solutions at 298 K was studied. The same compensation temperature Tc was found for both free base
