4-Methyl-2-(4-octyl-phenylazo)-phenol is a complex organic compound characterized by its molecular formula C23H26N2O. This chemical is a derivative of phenol, featuring a methyl group at the 4-position and an azo group (-N=N-) connecting a 4-octyl-phenyl moiety to the 2-position of the phenol ring. The presence of the octyl chain imparts lipophilic properties, which can influence its solubility and interactions with other molecules. 4-Methyl-2-(4-octyl-phenylazo)-phenol is often used in the synthesis of dyes and pigments due to its ability to form colored compounds. Its specific structure and properties make it a valuable component in various industrial applications, particularly in the production of colorants for textiles, plastics, and other materials.

Check Digit Verification of cas no

The CAS Registry Mumber 3181-21-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,8 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3181-21:
(6*3)+(5*1)+(4*8)+(3*1)+(2*2)+(1*1)=63
63 % 10 = 3
So 3181-21-3 is a valid CAS Registry Number.

Aryliminodimagnesium Reagents. XIX. Effects of Miscellaneous Metal Halides on Oxidative Self-Coupling of the Reagent, and on Its Condensation with Nitrobenzene. A New Preparative Route to o,o'-Dihydroxyazobenzene

Okubo, Masao,Shiku, Haruko

, p. 196 - 201 (2007/10/02)

Fourteen metal halides (MXn) were each added to the solution of aryliminodimagnesium (p-RC6H4N(MgBr)2, IDMg) in tetrahydrofuran, and the effect of MXn on relative yields of products was examined in the following three IDMg reactions: (A) oxidative coupling leading to symmetrical azobenzene, (B) condensation with nitrobenzene, and (C) condensation with o-hydroxy-substituted (o-HO) nitrobenzene.Reaction A was promoted by addition of CuCl2, and the yield of azoxybenzenes in reaction B was improved by addition of NiCl2 or CdCl2.Reaction C was similarly modified by addition of CdCl2 so as to improve the yield of o-HO-azoxybenzenes.Their acetyl derivatives underwent a facile photoinduced migration of azoxy oxygen and were successively hydrolyzed to afford bidentate chelating agents, o,o'-(HO)2-azobenzenes.
