Molecular Structure: Single azo class
Molecular Weight: 1026.25
CAS Registry Number:93050-80-7
Manufacturing Methods : the between 1-(3-Aminophenyl)urea and 2,4,6-Trichloro-1,3,5-triazine first condensation, 7-Aminonaphthalene-1,3,6-trisulfonic acid diazo, and condensation products coupled, again with a between, 2-(3-Aminophenylsulfonyl)ethyl hydrogen sulfate condensation, and then salting-out.
Properties and Applications: red light yellow. Orange powder. Soluble in water, in the water solubility of 80 g/L. After dyeing fabric as the red light yellow, in dye bath of metal ions in iron, a little yellow color a little dark; Copper ions in that red light shadow change. The dye move color performance for grade 5, neutral white a category 5, white alkaline for 3 ~ 4 levels. Mainly used for cellulose fiber dyeing, suitable for polyester/cotton, polyester/stick blended fabric dyeing of a bath.
