Please, can you explain me the meaning of the number of the dye name? For example, “reactive red 239”, what is the meaniing of “239”?
Many thanks!!![:)](http://www.worlddyevariety.com/wp-includes/images/smilies/simple-smile.png)
The structure in the figure is incorrect. Reactive Red 239 should have 31 Carbons. It has the same structure as Reactive Red 241, just as the acid.
