Application :

In the field of histology, Fast Sulphon Black F is used as a staining agent, often in combination with other dyes, to enhance the visualization of cellular structures, tissues, and biological samples under a microscope.
The dye finds application in various analytical chemistry techniques, such as spectrophotometry and chromatography, where it is used as a detection or labeling agent for the analysis of specific compounds.
Fast Sulphon Black is purple when complexed with copper, and turns green when titrated against EDTA, as the EDTA displaces it, being the better complexing agent due to the chelate effect.

Benefits :

Intense black color, making it a valuable colorant in applications where a strong, uniform black hue is desired
Exhibits good fastness properties
Water-soluble and versatile
