Yintoni i-4,4'-Diamino-2,2'-stilbenedisulfonic acid CAS 81-11-8?

4,4 '- diaminodiphenyl-2,2' - i-disulfonic acid ikwiklasi yeekhompawundi ze-stilbene kwaye ingalungiswa nge-hydrogenation yeekhompawundi zayo ezithathelwe indawo yi-nitro. 4,4 '- Diamino-2,2' - i-stilbenedisilfonic acid yikristale etyheli enesimo senaliti esityheli esifana ne-hygroscopic. Inyibilika kancinci emanzini, inyibilika kwi-ethanol nakwi-ether, inyibilika lula kwizisombululo ze-alkaline.
