Product Application of 2-[(4-Aminophenyl)sulfonyl]ethyl hydrogen sulfate CAS#2494-89-5

Para-ester is one of the important intermediates of reactive dyes, and is used to synthesize EF, KN, M/KM, ME and other reactive dyes containing vinyl sulfone groups. The production proportion of reactive dyes containing vinyl sulfone groups has increased significantly year by year, and has now developed into the largest type of reactive dyes, occupying a very important position in the production and research of reactive dyes.
