| Hazard Information | Back Directory | [Uses]
2-Amino-5-chlorobenzenesulfonic Acid can be used as reactant/reagent in determination of the dissociation constants of some newly synthesized arylhydrazones of indane-1,3-dione. | [Production Methods]
5-Chloroorthanilic acid is manufactured by baking 4- chloroaniline hydrogensulfate in vacuo; after the mass has been pumped into water, the acid is neutralized with calcium oxide; the solution is suitable for use in the manufacture of azo dyes.
