4,4’-Diamino-2,2’-stilbenedisulfonic acid (also known as amsonic acid) is used in the synthesis of dyes and optical brighteners or fluorescent whitening agents. Amsonic acid possesses estrogenic activity, and thus provided a possible mechanistic explanation for the complaints of impotency in factory workers exposed to this compound. In the 2-year feed studies on rodents, there was no evidence of carcinogenic activity of amsonic acid, in male or female F344/N rats receiving 12,500 or 25,000 ppm. In addition, there was no evidence of carcinogenic activity of this compound in male or female B6C3F1 mice receiving 6,250 or 12,500 ppm.

Sample Use Guides
Toxicology Studies in rodents: F344/N rats and B6C3F1 mice of each sex for 14 days, 13 weeks, and 2 years.
Groups of five rats and five mice of each sex were given 0, 6,250, 12,500, 25,000, 50,000, or 100,000 ppm 4,4'-diamino-2,2'-stilbenedisulfonic acid, disodium salt, in feed for 14 days.
Groups of 10 rats and 10 mice of each sex were given 0, 6,250, 12,500, 25,000, 50,000, or 100,000 ppm 4,4'-diamino-2,2'-stilbenedisulfonic acid, disodium salt, in feed for 13 weeks.
Groups of 60 rats of each sex were given 0, 12,500 or 25,000 ppm and groups of 60 mice of each sex were given 0, 6,250, or 12,500 ppm 4,4'-diamino-2,2'-stilbenedisulfonic acid, disodium salt, in feed for up to 103 weeks.
Route of Administration:
Oral
Genetic toxicology studies: 4,4'-Diamino-2,2'-stilbenedisulfonic acid was not mutagenic in Salmonella typhimurium strains TA100, TA1535, TA1537, or TA98 with or without S9 metabolic activation. 4,4'-Diamino-2,2'-stilbenedisulfonic acid did not induce sister chromatid exchanges or chromosomal aberrations in Chinese hamster ovary cells in the presence or absence of S9.
