L-Amino-2-methylanthraquinone

Use of the intermediates l-amino-2,4 dibromoanthraquinone and l-aminO 4 bromO 2 methylanthraquinone leads to similar dyes, exemplified by Cl Acid Blue 78 (6.34 X = Br) and Cl Acid Blue 47 (6.34 X = CH3) respectively in the production of these two dyes, sulphonation is the final step.
