1. Ukuncibilika: Emanzini,I-Nigrosine Blackyakha isixazululo esiluhlaza okwesibhakabhaka-onsomi, ebonisa ukuncibilika okuhle, okuyivumela ukuthi ihlanganyele namaqembu e-hydroxyl noma ama-amino ezintweni ze-fiber, ngaleyo ndlela izuze ukudaya.Ukwengezwa kwesisombululo se-sodium hydroxide kubangela ukwakheka kwemvula e-brownish-purple.I-Nigrosine Black iyancibilika ku-ethanol, ibonisa umbala oluhlaza okwesibhakabhaka, futhi ku-asidi ye-sulfuric egxilile, ibuye ibonakale eluhlaza okwesibhakabhaka;lapho ihlanjululwa, ishintsha ibe nsomi ngokwakheka kwezulu.I-Nigrosine Black icishe ingancibiliki ku-ether, i-acetone, i-benzene, i-chloroform, i-petroleum ether, nopharafini owuketshezi.
2. Isitoreji:I-Nigrosine Blackkufanele igcinwe kude nokuxhumana nama-oxidizing agents ngesikhathi sokusetshenziswa.Lapho ugcina, qiniseka ukuthi isitsha sokugcina sivalwe ngokuqinile futhi usigcine endaweni epholile neyomile.
