Description

4-Amino-4'-nitrostilbene-2,2'-disulfonic acid serves as an important stilbene intermediate. It acts as a monomer. Further, it is used in the synthesis of a series of direct dyes such as direct lightfast fluorescent yellow 7GL, 6GL, 5GL, 4GL, 3GL and 2GL. In addition to this, it is used to prepare direct yellow DN-FR, orange F3G; yellow 3RLL, green GND and direct Black DN-EX.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
