3-Nitro-1H-indole is an organic compound with the chemical formula C8H6N2O2. It is a yellow crystalline solid that is soluble in common organic solvents such as ethanol, methanol, and acetone. 3-Nitro-1H-indole is a derivative of indole, a heterocyclic aromatic organic compound that contains a benzene ring fused to a pyrrole ring. The nitro group (-NO2) is attached to the 3-position of the indole ring, which significantly affects its chemical properties and reactivity. 3-Nitro-1H-indole is an important intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds due to its versatile chemical properties and potential for further functionalization. It is also used in the preparation of dyes and pigments, as well as in the study of chemical reactions involving indole derivatives.

Check Digit Verification of cas no

The CAS Registry Mumber 4770-03-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,7 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4770-03:
(6*4)+(5*7)+(4*7)+(3*0)+(2*0)+(1*3)=90
90 % 10 = 0
So 4770-03-0 is a valid CAS Registry Number.

Regioselective nitration of 3-acetylindole and its N-acyl and N-sulfonyl derivatives

Ottoni, Olivia,Cruz, Rosimeire,Krammer, Norbert H.

, p. 1117 - 1120 (1999)

3-Acetylindole reacts regioselectively with NO2BF4 in the presence of SnCl4 to produce 3-acetyl-5-nitroindole or 3-acetyl-6-nitroindole, depending on the temperature, both in excellent yields.

Synthesis of Benzothienobenzofurans via Annulation of Electrophilic Benzothiophenes with Phenols

Krishnan, Akhil R.,Babu, Sheba Ann,Nitha,Krishnan, Jagadeesh,John, Jubi

supporting information, p. 1814 - 1819 (2021/03/08)

We have developed a metal-free, mild, and green synthetic route toward benzothieno[3,2-b]benzofurans by the annulation of 3-nitrobenzothiophene with phenols. The reaction was found to be general with a range of substituted phenols. In addition, we could extend the methodology for the synthesis of pentacenes and could demonstrate the synthesis in gram-scale. Moreover, we extended the strategy for the synthesis of benzothieno[2,3-b]benzofurans by starting from 2-nitrobenzothiophenes.

A mild and efficient method for the mononitration of aromatic compounds by cerium (III) ammonium nitrate in acetic anhydride

Tanemura, Kiyoshi,Suzuki, Tsuneo,Nishida, Yoko,Satsumabayashi, Koko,Horaguchi, Takaaki

, p. 497 - 499 (2007/10/03)

A mild and efficient method for the mononitration of aromatic and olefinic compounds is described. This method is especially useful for active substrates.
