Molecular Formula:C₁₉H₁₂BrCl₂N₅Na₂O₈S₂

Molecular Weight: 699.25

CAS Registry Number:12226-61-8

Manufacturing Methods : 2-Amino-4-(2-bromoacrylamido)benzenesulfonic acid diazo, and 2,5-Bichloro-4-(3-methyl-5-oxo-4,5-dihydropyrazol-1-yl)benzenesulfonic acid coupling.

Properties and Applications: green light yellow. Green light yellow powder, 90 ℃ water solubility in for 100 g/L. For dyed in acid bath dyeing, pH control in 5 ~ 6 between, general join 1% of leveler PW-BX, dye bath temperature rise to 70 ~ 75 ℃ to heat preservation 15 to 16 minutes, depending on the dyeing depth and decide. Such as dyeing depth greater than 10% need to use liquid ammonia in post-processing, pH value of 8.5, time 15 minutes, temperature of 80 ℃. The dye levelness is bad, but good color fastness, dyeing fabrics after bright color. Can be used for wool fiber, tops, scattered wool dyeing, also can be used for wool and silk printing.
