Benzenamine, 3-methyl-4-(phenylazo)-, also known as 3-Methyl-4-(phenylazo)aniline or 4-(phenylazo)-o-toluidine, is an organic compound with the chemical formula C13H13N3. It is a derivative of aniline, featuring a methyl group at the 3rd carbon and a phenylazo group at the 4th carbon. This yellow crystalline solid is soluble in organic solvents and has a melting point of approximately 95-97°C. The compound is primarily used as a chemical intermediate in the synthesis of dyes, pigments, and other organic compounds. It is also known for its potential applications in the pharmaceutical industry and as a reagent in analytical chemistry. Due to its azo group, it can form various colored compounds, making it valuable in the production of azo dyes. However, it is important to note that Benzenamine, 3-methyl-4-(phenylazo)- may have certain health and environmental hazards, and appropriate safety measures should be taken during its handling and use.

6657-16-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6657-16-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,5 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6657-16:
(6*6)+(5*6)+(4*5)+(3*7)+(2*1)+(1*6)=115
115 % 10 = 5
So 6657-16-5 is a valid CAS Registry Number.

Clay catalysed facile rearrangement of diazoaminobenzene to p-aminoazobenzene

Pitchumani, K.,Venkatachalapathy, C.,Sivasubramanian, S.

, p. 187 - 189 (2007/10/03)

Rearrangement of diazoaminobenzene in the presence of acidic cation-exchanged K10-montmorillonite gives exclusively p-aminoazobenzene at room temperature within three hours.

Transitional-Metal-Activated Organic Compounds, XXXV. - ortho-Alkylation of Aromatic Azo Compounds with Alkyllithium Reagents and Lithium Trimethylferrate(1-)

Kauffmann, Thomas,Jordan, Jan,Sander, Joerg

, p. 153 - 155 (2007/10/02)

Whereas methyllithium reacts with 4-(dimethylamino)-, 4-amino-, and 4-methoxyazobenzene, respectively, by ortho-methylation of the electron-rich phenyl residue of the azo compound, (CH3)3FeLi ortho-methylates the less electron-rich phenyl group of 4-(dimethylamino)azobenzene.A mechanistic rationalization is given for both reaction modes.Key Words: Lithium, organo compounds / Iron, organo compounds / Azo compounds / ortho-Alkylation
