The main use of this chemical is for the dyeing of polyester and its blends. And this chemical can be prepared by 5-Nitroanthranilonitrile and 3-Ethylanilinopropiononitrile. First, you should nitride the 5-Nitroanthranilonitrile. Then you can use the product act with 3-Ethylanilinopropiononitrile. Finally, after filtering, grind and air-dry, you can get the Disperse Red 73.
