1-[(5-Chloro-2-methoxyphenyl)azo]-2-naphthol is an organic compound characterized by its azo group, which is a diazenyl functional group (-N=N-). This particular compound features a 2-naphthol moiety, which is a naphthalene ring with a hydroxyl group at the 2-position. The naphthol is substituted with an azo group that is attached to a 5-chloro-2-methoxyphenyl ring. The presence of the chlorine atom at the 5-position and the methoxy group at the 2-position on the phenyl ring contributes to the compound's chemical properties and reactivity. 1-[(5-Chloro-2-methoxyphenyl)azo]-2-naphthol is often used as a dye or pigment due to its color-imparting properties.

6548-36-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6548-36-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,4 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6548-36:
(6*6)+(5*5)+(4*4)+(3*8)+(2*3)+(1*6)=113
113 % 10 = 3
So 6548-36-3 is a valid CAS Registry Number.

Fe(HSO4)3 as an Efficient Catalyst for Diazotization and Diazo Coupling Reactions

Rahimizadeh, Mohammad,Eshghi, Hossein,Shiri, Ali,Ghadamyari, Zohreh,Matin, Maryam M.,Oroojalian, Fatemeh,Pordeli, Parvaneh

, p. 716 - 719 (2013/05/08)

Diazo coupling reactions of aromatic amines with 2-naphthol in a green, efficient and easy procedure is described. Ferric hydrogensulfate catalyses this reaction in water at room temperature and short reaction time with high yields. The antibacterial activities of the synthesized compounds against four pathogenic bacteria are also investigated.

New dry arenediazonium salts, stabilized to an exceptionally high degree by the anion of o-benzenedisulfonimide

Barbero, Margherita,Crisma, Marco,Degani, Lacopo,Fochi, Rita,Perracino, Paolo

, p. 1171 - 1175 (2007/10/03)

Arenediazonium o-benzenedisulfonimides 3 (20 examples, yield >90%) were prepared in the dry state by diazotization of aromatic amines with (-pentyl nitrite and o-benzenedisulfonimide in glacial acetic acid or formic acid at 0-5°C. Unlike most diazonium salts in the dry state, salts 3 are very highly stable.
