Additional information
In a National Center for Biotechnology Information, U.S. National Library of Medicine report (2016), mentioned that the 4-aminoazobenzene-3,4'-disulphonic acid was appeared to be Organic powder solid.
In a Center for Chemical Hazard Assessment, Syracuse Research Corporation report (1981), mentioned that the4-aminoazobenzene-3,4'-disulphonic acid wasappearedto be Organic solid in needles form with dark violet colour.
