Uses:

As Reactive Red 238 is no longer a commercially available textile dye, exposure to Reactive Red 238 in the future, occupational or otherwise, is not likely. As a result, we no longer consider  Reactive Red 238  to be relevant and we have decided to stop producing and selling Reactive Red 238 (R-009B) as of 1st of January 2018. 

Azo dye belonging to the reactive dye class for coloring cotton, wool, silk and polyamide textiles. May cause allergic conjunctivitis, allergic rhinitis and occupational asthma.
