77474-65-8 Usage
General Description
2,9,16,23-Tetrakis(phenylthio)-29H,*31H-phthalocyanine, also known as TPP, is a synthetic pigment and dye that belongs to the phthalocyanine family. It is characterized by a large, planar, aromatic macrocyclic ring with four isoindole units linked by nitrogen atoms at the 131 and 79 positions. TPP is used as a blue or green pigment in inks, paints, and plastics due to its high stability, strong color, and resistance to fading. It is also utilized in the production of organic solar cells, as a sensitizer in photodynamic therapy, and as a catalyst in organic synthesis. 2,9,16,23-TETRAKIS(PHENYLTHIO)-29H,*31H- PHTHALOCYAN has potential applications in the fields of photovoltaics, medicine, and materials science due to its unique optical, electrical, and chemical properties.
Check Digit Verification of cas no
The CAS Registry Mumber 77474-65-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,7 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77474-65:
(7*7)+(6*7)+(5*4)+(4*7)+(3*4)+(2*6)+(1*5)=168
168 % 10 = 8
So 77474-65-8 is a valid CAS Registry Number.

, p. 736 - 741 (2018/06/14)
The methods of synthesis of 4-tert-butyl-5-sulfanylphenyl-and 4-tert-butyl-5-(4'-carboxyphenylsulfanyl) phthalonitriles have been developed and on their basis the corresponding octa-substituted phthalocyanines have been prepared. The effect of the structure of the above phthalocyanine derivatives on their electronic absorption spectra and parameters of thermal degradation in the presence of air oxygen were studied.
