Properties and Applications
red light purple. brown-red powder, soluble in alcohol. The strong sulfuric acid in colorless, diluted red for yellow light. In dyeing calcium and magnesium ions not sensitive, encounter iron ion colored light slightly influence, copper ions in big effect. Dye bath appropriate pH value for 3 to 8, in dyeing and printing not alkali resistance. The dyes red light for purple, suitable for polyester/cotton blended fabric dyeing, and have a good color fastness to dry. Suitable for high temperature high pressure and hot melt dyeing method, hot melt temperature of 210 ~ 220 ℃. In three vinegar on fiber dyeing, colored light and polyester similar, is not suitable for dyeing two vinegar fiber, polyamide fiber and acrylic. But in polyester fabric weaving direct printing, cannot be printing the impression of the discharge. And Disperse Violet 26?and the same chemical structure.

Check Digit Verification of cas no
The CAS Registry Mumber 6408-72-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6408-72:
(6*6)+(5*4)+(4*0)+(3*8)+(2*7)+(1*2)=96
96 % 10 = 6
So 6408-72-6 is a valid CAS Registry Number.

Paragraph 0036; 0037; 0038; 0043; 0048; 0053; 0054, (2018/11/03)
The invention discloses a solvent red 59 synthesis process, in order to 1, 4 - dinitro - 2, 3 - two chloroanthraquinone, phenol sodium as raw materials, the organic solvent in the presence of O-chlorobenzene to generate a condensation reaction to produce 1, 4 - dinitro - 2, 3 - [...] anthraquinone, 1, 4 - dinitro - 2, 3 - [...] anthraquinone and then by further reduction to produce 1, 4 - diamino - 2, 3 - [...] anthraquinone. Because of the 1, 4 - dinitro - 2, 3 - dichloro anthraquinone activity and low 1, 4 - diamino - 2, 3 - dichloro anthraquinone of high activity, the invention the reaction is easy to carry out, so greatly shortens the reaction time; and the reaction less side reaction, high yield, insoluble matter is greatly reduced, while at the same time, this synthetic route will not produce a large amount of salt-containing waste water, the process is relatively clean and environmental protection.
