Labile aliphatic molecules

The most familiar derivatives of diaminostilbene disulfonic acid are the 4,4 -bis-(triazinyl-amino)-stilbene disulfonic acids. Compounds of this type are produced by converting one molecule of 4,4 -diaminostilbene-2,2 -disulfonic acid with two molecules of cyanuric chloride (5) to yield compound 6 and then substituting the remaining labile halogen atoms with nonchromophoric substituents such as aUcoxy or phenoxy groups, but generally by means of unsubstituted, substituted, aliphatic, or aromatic amine groups (examples are compounds 7 and 8).
