C.I.Acid Blue 169,C.I.15025,CAS 6370-10-1,547.81,C16H8ClN3Na2O10S2,Lanamid Blue BL

Molecular Formula:C₁₆H₈ClN₃Na₂O₁₀S₂

Molecular Weight: 547.81

CAS Registry Number:6370-10-1

Manufacturing Methods : 5-Chloro-2-methoxy-4-nitrobenzenamine diazo, and 1-Naphthol-4,8-disulfonic acid coupling, and then with aqueous acid chromium common heating (125 ~ 135 ℃), make its formed chromium complex. In the complex process medium armor oxygen radicals displacement into hydroxyl, and 4-from sulfonic acid sodium base there will be 20% off.
