Introduction and application of CAS 2379-74-0 |ORALITH BRILLIANT PINK R
Introduction: Reduce pink R to thioindigo dyes. The main method to obtain thioindigo dyes is to oxidize unsubstituted or substituted benzo[b]thiophene-3 or naphtho[2,3-b]thiophene, using various Oxidants such as bromine in chlorosulfonic acid medium, polysulfides, oxygen in the presence of copper salts, etc.
Purpose: Pink R is used for dyeing cotton, viscose fiber, silk, wool, nylon, vinylon and printing cotton. Chemicalbook has good level dyeing properties, medium affinity, and bright and pure color. It can be used alone or combined with GGN, brown RRD, Qinglian RH, etc. It is also used in the manufacture of organic pigments, plastic coloring, etc.
Usage: Mainly used for dyeing and printing cotton fabrics. It can also be used as a pigment for coloring plastics.
