3179-96-2 Usage
Description
1-(methylamino)-4-(phenylamino)anthraquinone is an anthraquinone derivative with a methylamino group at the 1-position and a phenylamino group at the 4-position. It exhibits a bright blue color and is soluble in solvents such as acetone, ethanol, and benzene.
Uses
Used in Textile Industry:
1-(methylamino)-4-(phenylamino)anthraquinone is used as a dye for standard (polyamide) textiles. It provides good ironing fastness, light fastness, perspiration fastness, and washing fastness, with ratings ranging from 4 to 5 according to ISO standards. It also helps prevent fading and staining in textiles.
Preparation
1-(Methylamino)anthracene-9,10-dione brominated, with aniline condensation.

Check Digit Verification of cas no
The CAS Registry Mumber 3179-96-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,7 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3179-96:
(6*3)+(5*1)+(4*7)+(3*9)+(2*9)+(1*6)=102
102 % 10 = 2
So 3179-96-2 is a valid CAS Registry Number.

STRUCTURE OF THE BORATE COMPLEXES OF α-AMINO AND α-HYDROXY-9,10-ANTHRAQUINONES AND THEIR REACTION WITH AMINES

It was shown by 13C NMR that a redistribution of the bonds with partial localization of the 1,5- and 1,10-anthraquinonoid structures occurs during the transition from 1,5-diamino(dihydroxy)- and 1-amino(hydroxy)-9,10-anthraquinones respectively to their borate complexes.For this reason the boroacetates and fluoroborates of 1,5-dihydroxyanthraquinonones, 1-aminoanthraquinones, their N-alkyl and N-aryl derivatives, and 1,5-dihydroxyanthraquinone are capable of entering into amination under the influence of aromatic amines with substitution of the hydrogen atom at position 4 under mild conditions with the participation of atmospheric oxygen as oxidizing agent
