α,α-5,15-bis(2'-aminophenyl)-2,8,12,18-tetraethyl-3,7,13,17-tetramethylporphyrin is a complex organic compound belonging to the porphyrin class. Porphyrins are large heterocyclic molecules with a central ring structure, consisting of four pyrrole subunits interconnected by methine bridges. This specific compound features two aminophenyl groups at the 5 and 15 positions, and is further characterized by the presence of four ethyl groups at the 2, 8, 12, and 18 positions, as well as four methyl groups at the 3, 7, 13, and 17 positions. These substituents contribute to the compound's unique chemical properties and potential applications, such as in the field of photodynamic therapy, where porphyrin derivatives are used for their ability to absorb light and generate reactive oxygen species, or in the development of novel materials with specific optical and electronic properties.

Check Digit Verification of cas no

The CAS Registry Mumber 94111-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,1,1 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94111-50:
(7*9)+(6*4)+(5*1)+(4*1)+(3*1)+(2*5)+(1*0)=109
109 % 10 = 9
So 94111-50-9 is a valid CAS Registry Number.

Synthesis and Characterization of Blocked and Ligand-Appended Hemes Derived from Atropisomeric meso-Diphenylporphyrins

Young, Richard,Chang, C. K.

, p. 898 - 909 (2007/10/02)

The synthesis of a series of sterically blocked and imidazole-appended meso-diphenyletioporphyrins is described.These hybrid porphyrins have good solubility and spectroscopic properties of β-substituted porphyrins as well as the orientation specificity of ortho-position-derivatized tetraphenylporphyrins.The effectiveness of the blocking groups is demonstrated by ferric hemin hydroxide formation in the doubly protected trans-5,15-bis-2,8,12,18-tetraethyl-3,7,13,17-tetramethylporphine, characterized by UV-visible, 1H NMR, and IR spectra and cyclic voltammetry.The advantage of the m-benzyl linkage in enforcing imidazole coordination to ferric hemes is demonstrated by 1H NMR studies on various type of imidazole-appended heme complexes.Several potential binucleating systems have also been prepared by incorporating nonheme chelating ligands to the hybrid porphyrins.
