61951-82-4 Usage
Synthesis
Cyanuric chloride is condensed with H acid, then condensed with p-phenylenediamine, and then diazotized with anthranilic acid, coupled with the condensate to synthesize Reactive Red 120.
Definition
ChEBI: A bis(azo) compound that consists of a benzene core having two (4-amino-6-chloro-1,3,5-triazin-2-yl)amino groups attached at positions 1 and 4 and which in turn have 5-hydroxy-6-[(2-sulfophenyl)diazenyl]-2,7-disulfonaphthalen-4-yl groups attached to their
-amino functions.
Preparation
2-Aminobenzenesulfonic acid diazo, and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, and 2,4,6-Trichloro-1,3,5-triazine first condensation, its product (2 Moore) and Benzene-1,4-diamine?second condensation.
Properties and Applications
colourful red blue light. Red uniform powder. Soluble in water, 50 ℃ in the water when the solubility of more than 140 g/L. Dyeing color for colourful blu-ray red, dyeing in light of iron ion slightly to yellow (category 4); Copper ions in turn light blue (level 2). Compatibility is high, the reaction of the medium, and easy to wash the gender is good. Mainly used for cotton or viscose fiber volume dye and disseminated, also can be used for direct printing, also suitable for polyester/cotton, polyester/stick blended dyeing.

Check Digit Verification of cas no
The CAS Registry Mumber 61951-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,5 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 61951-82:
(7*6)+(6*1)+(5*9)+(4*5)+(3*1)+(2*8)+(1*2)=134
134 % 10 = 4
So 61951-82-4 is a valid CAS Registry Number.
