43193-60-8 Usage

General Description

Pyrazinetetracarboxylic acid is an organic compound with the molecular formula C8H4N2O8. Also known as PTCA, it is a derivative of pyrazine and is composed of a pyrazine ring with four carboxylic acid groups attached to it. This chemical is primarily used as a complexing agent in the synthesis of coordination compounds and metal-organic frameworks. It has also been studied for its potential use in pharmaceuticals, as well as in electronic and materials applications due to its unique structural and coordination properties. Additionally, PTCA has been investigated for its potential use as an antiviral and antimicrobial agent. However, further research is needed to fully explore and understand its potential uses and applications.

Check Digit Verification of cas no

The CAS Registry Mumber 43193-60-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,1,9 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 43193-60:
(7*4)+(6*3)+(5*1)+(4*9)+(3*3)+(2*6)+(1*0)=108
108 % 10 = 8
So 43193-60-8 is a valid CAS Registry Number.

Self-assembly of alternating left- and right-handed infinite Cd(II) helicates into a 2D open framework structure

Ghosh, Sujit K.,Bharadwaj, Parimal K.

, p. 119 - 122 (2006)

Pyrazine-2,3,5,6-tetracarboxylic acid (ptcH4) reacts with Cd(NO3)2·6H2O at room temperature in the presence of pyridine to form a 2D open framework built from alternating left- and right-handed helicates with the empirical formula, {[Cd2(ptc)·(py)5·H2O]·5H2O·py}n, 1. Lattice water and pyridine molecules form an intricate array of H-bonding with the 2D sheets leading to a 3D structure. This compound crystallizes in the monoclinic space group C2/c with the following lattice parameters-a=24.103(2), b=13.480(5), c=29.176(4) A?, β=109.427(3)°, V=8940(4) A?3, Z=8, R1=0.0513, wR2=0.1552, S=1.085.

Facile construction of two-dimensional coordination polymers with a well-designed redox-active organic linker for improved lithium ion battery performance

Liu, Jingwei,Zhang, Lin,Li, Huanhuan,Zhao, Peng,Ren, Peng,Shi, Wei,Cheng, Peng

, p. 602 - 608 (2019)

A well-designed redox-active organic linker, pyrazine-2,3,5,6-tetracarboxylate (H4pztc) with brimming active sites for lithium ions storage was utilized to construct coordination polymers (CPs) via a facile hydrothermal reaction. Those two isostructural two-dimensional (2D) CPs, namely [M2(pztc)(H2O)6]n (M=Co for 1 and Ni for 2), delivered excellent reversible capacities and stable cycling performance as anodes in lithium ion batteries. As demonstrated in electrochemical studies, 1 and 2 can achieve highly reversible capacities of 815 and 536 mA h g?1 at 200 mA g?1 for 150 cycles, respectively, best performed for the reported 2D-CP-based anode materials. The electrochemical mechanism studies showed that the remarkable performances can be ascribed to the synergistic Li-storage redox reactions of metal centers and organic moieties. Our work highlights the opportunities of using a well-designed organic ligand to construct low-dimensional CPs as new type of electrode materials for advanced lithium ion batteries.

1D slide-fastener-like coordination polymers of Mn(II) derived from pyrazine-2,3,5,6-tetracarboxylic acid

Gao, Hong-Ling,Zhang, Yan-Ping,Yang, Ai-Hong,Fang, Su-Rong,Cui, Jian-Zhong

experimental part, p. 97 - 100 (2009/05/08)

Two new 1D slide-fastener-like coordination polymers {[Mn2(pztc)(phen)2(H2O)2]·4H2O}n (1) and {[Mn2(pztc)(bpy)2(H2O)2]·2H2O}n (2) have been synthesized by the reactions of pyrazine-2,3,5,6-tetracarboxylic acid (pztcH4) and Mn(OAc)2·4H2O in the presence of 1,10-phenanthroline (phen) or 2,2′-bipyridine (bpy) under hydrothermal conditions and characterized by elemental analyses, FT-IR, TGA and X-ray diffraction. In complex 1 and 2, metal ions are bridged by pyrazine-2,3,5,6-tetracarboxylate, coordinating in a hexadentate manner, so forming 1D polymeric chains. The remaining coordination sites of the metal ions are occupied by one O atom of water molecule and two N atoms of the terminal ligand (phen or bpy). IR spectra and thermal analysis data are in agreement with the crystal structure.
