Odorless yellowish microscopic needles or cream-colored powder. pH approximately 4.3 at 30 g/L water (suspension).
공기와 물의 반응
Insoluble in water.
반응 프로필
4,4'-Diamino-2,2'-stilbenedisulfonic acid is incompatible with iron. 4,4'-Diamino-2,2'-stilbenedisulfonic acid forms sparingly water-soluble, crystalline salts with many bisquaternary ammonium bases.
화재위험
Flash point data for 4,4'-Diamino-2,2'-stilbenedisulfonic acid are not available; however, 4,4'-Diamino-2,2'-stilbenedisulfonic acid is probably combustible.

For the environment, various NOEC and LC50 values were gained from test results; LC50 = > 1000 mg/l (acute fish); EC50 = 210 mg/l (acute daphnia); EC50 = 76 mg/l (acute algae); NOEC = 32 mg/l (algae); NOEC = 37 mg/l (longterm daphnia reproduction). The lowest toxicity result (72h-NOEC, biomass, for Selenastrum capricornutum, 32 mg/l) was used to derive a PNEC. An assessment factor of 100 was used according to the OECD Provisional Guidance for Initial Assessment of Aquatic Effects. Thus, PNEC of 4,4'-Diamino-2,2'-stilbenedisulfonic acid is 0.32 mg/l in the present report. The PEC is lower than the PNEC. The environmental risk is presumed to be low.
