118-20-7 Usage

General Description

[2,9,16,23-tetranitro-29H,31H-phthalocCopper phthalocyanine, or [2,9,16,23-tetranitro-29H,31H-phthalocyaninato(2-)-N29,N30,N31,N32]copper, is a complex chemical compound with a copper atom at its core. Phthalocyanines are a class of synthetic macrocyclic compounds that are widely used in various applications such as dyes, pigments, and semiconductor materials. The nitro groups in the molecule are electron-withdrawing, and the copper center makes the molecule highly reactive. [2,9,16,23-tetranitro-29H,31H-phthalocyaninato(2-)-N29,N30,N31,N32]copper is known for its intense blue color and is commonly used as a blue pigment in paints and plastics. Its unique chemical structure and properties make it suitable for a wide range of industrial and technological applications.

Check Digit Verification of cas no

The CAS Registry Mumber 118-20-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118-20:
(5*1)+(4*1)+(3*8)+(2*2)+(1*0)=37
37 % 10 = 7
So 118-20-7 is a valid CAS Registry Number.

Self-assembly of phthalocyanine and polyacrylic acid composite multilayers on cellulose nanofibers

Mao, Xue,Ding, Bin,Wang, Moran,Yin, Yanbing

, p. 839 - 844 (2010)

In this study, a novel nanocomposite multilayers was deposited on the electrospun nanofibrous mats by an electrostatic layer-by-layer (LBL) self-assembly technique. The positively charged water-insoluble 2,9,16,23-tetraaminophthalocyanine copper (CuTaPc) and the negatively charged water-soluble poly(acrylic acid) (PAA) were alternately deposited on the surface of negatively charged nanofibrous cellulose mats. The cationic CuTaPc was synthesized and characterized by UV-Vis and Fourier transform infrared (FT-IR) spectroscopy. The template nanofibrous cellulose mats were obtained from the alkaline hydrolysis of electrospun nanofibrous cellulose acetate mats. The resultant nanofibrous mats were characterized by scanning electron microscopy (SEM) and FT-IR spectroscopy. The SEM images showed that the composite LBL structured films were homogeneously deposited on the surface of the nanofibers. The diameters of nanofibers increased with the number of deposition bilayers. The average thickness of each CuTaPc/PAA bilayer is about 10 nm. Additionally, the FT-IR spectra results also indicated that the CuTaPc and PAA were coated on the nanofibrous cellulose mats.

Synthesis and spectral studies on substituted metal (II)-tetra-1-(thiophene-2-yl)methanimine phthalocyanine complexes

Fasiulla,Yashoda

, p. 1526 - 1532 (2018/07/15)

The synthesis, characterization of symmetrically substituted transition metal (ΙΙ)–tetra-1-(thiophene-2-yl) methaniminephthalocyanine complexes by condensation of tetraamino phthalocyanines with 2-thiophenecarboxaldehyde had been prepared. The structural and characterization of theblue colour tetra -1-(thiophene-2- yl)methanimine phthalocyanine complexesare elucidated by using a number of analytical techniques like FT-Infrared, UV-Vis spectroscopy, XRD, magnetic measurements and thermo-gravimetric analysis.The kinetic parameters and thermal decomposition of synthesized phthalocyanines complexes were calculated using thermo-gravimetric analytical data.

Synthesis and evaluation of antibacterial activity of water-soluble copper, nickel and zinc tetra (n-carbonylacrylic) aminephthalocyanines

Pavaskar,Patil,Furtado,Salker

, p. 4300 - 4307 (2013/09/02)

Water-soluble copper, nickel, and zinc tetra (n-carbonylacrylic) aminephthalocyanines were synthesized with an aim to evaluate their role as therapeutic materials. They were characterized by UV-Vis spectrophotometer, infra-red spectra, elemental analysis, nuclear magnetic resonance, and thermogravimetry. Efforts were made to optimize the synthesis of intermediates and final products. Photoluminescence studies were carried out on these compounds. The investigation of antibacterial activity of these aqueous soluble phthalocyanines was carried out on Staphylococcus citreus, Serratia marcescens, Proteus vulgaris, Bacillus subtilis, and Pseudomonas fluorescence, showed good inhibitory activity.
