75497-74-4 Usage
Description
Disperse Blue 79:1 is a navy blue-gray powder that is soluble in acetone. It is a dye that is suitable for high temperature and high pressure dyeing, providing deep color and good sublimation fastness. However, it may not be ideal for certain types of fiber dyeing and can result in less vibrant colors when used with certain dyeing methods.
Uses
Used in Textile Industry:
Disperse Blue 79:1 is used as a dye for textile dyeing, particularly for high temperature and high pressure dyeing processes. It provides deep color and good sublimation fastness, making it suitable for various textile applications.
Used in Acrylic and Polyester Fiber Dyeing:
Disperse Blue 79:1 is used as a dye for acrylic and polyester fiber dyeing. However, it may not provide the most vibrant colors when used with certain dyeing methods.
Used in Reactive Dyeing:
Disperse Blue 79:1 can be used in reactive dyeing, but it may result in less level dyeing when used for piece dyeing. It is also sensitive to alkali and can be influenced by the presence of copper ions in the dye bath.
Used in Plasma Reactive Dyeing:
When used in plasma reactive dyeing, Disperse Blue 79:1 can result in a change in the color lightness, providing a unique effect for certain textile applications.
Preparation
2,4-Dinitro-6-bromoaniline?diazo, and Acetamide,N-[3-[bis[2-(acetyloxy)ethyl]amino]-4-methoxyphenyl]- coupling.
Check Digit Verification of cas no
The CAS Registry Mumber 75497-74-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,9 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75497-74:
(7*7)+(6*5)+(5*4)+(4*9)+(3*7)+(2*7)+(1*4)=174
174 % 10 = 4
So 75497-74-4 is a valid CAS Registry Number.

Synthesis and Spectral Characterization of Blue Dyes of the Benzene Series
Thiel, W.,Mayer, R.,Jauer, E.-A.,Modrow, H.,Dost, H.
, p. 497 - 514 (2007/10/02)
53 Donor-acceptor substituted azo dyes of the benzene series were prepared by diazonium-coupling reactions (1a-s) or halogen-cyanide exchange (->2a-x, 3a-j).Described are the preparation of the amines 4a-m and the coupling compounds 5a-t and the procedure of diazotizing and coupling.The colouristic and spectroscopic data show that compounds of the general formula 1 are excellent brilliant blue azo dyes usefull for dyeing polyester material.
