Izakhiwo Zomzimba Nezamakhemikhali Impushana emnyama. Incibilika ku-ethanol, i-toluene, i-acetone nezinye izincibilikisi. Ku-asidi ye-sulfuric egxilile, yayimnyama ngokunsomi, futhi ngemva kokuhlanjululwa, yaba luhlaza okwesibhakabhaka ngokumnyama, okuholela ekubeni kube nemvula eluhlaza okwesibhakabhaka kuye kokumnyama. Ukwengezwa kwe-hydrochloric acid egxilile kwisisombululo se-ethanol sikadayi kumnyama okwesibhakabhaka; Ukwengezwa kwesisombululo se-sodium hydroxide egxilile kuluhlaza okwesibhakabhaka obumnyama.
Sebenzisa Ibala lebhayoloji, lokungcolisa amagciwane namafutha, elisetshenziswa ku-histochemistry ukuhlukanisa upharafini namafutha ezilwane, amabala e-myelin, izinhlayiya zamangqamuzana amhlophe egazi kanye ne-Golgi apparatus staining, kanye nokungcoliswa okufana ne-lipid kumaseli nezicubu.

Black 3 CAS 4197-25-5 Isingeniso

I-Sudan Black B idayi yemvelo enegama lekhemikhali elithi methylene blue. I-crystalline powder emnyama eluhlaza okwesibhakabhaka nokuncibilika okuhle emanzini.
Ibuye isetshenziswe kabanzi ku-histology njenge-reagent staining ngaphansi kwe-microscope ukungcolisa amaseli nezicubu ukuze kubonwe kalula.

Indlela yokulungiswa kweSudan emnyama B ngokuvamile itholakala ngokusabela phakathi kweSudan III ne-methylene eluhlaza okwesibhakabhaka. I-Sudan Black B nayo ingatholakala ngokunciphisa ku-methylene blue.

Ulwazi olulandelayo lokuphepha kufanele lunakekelwe lapho kusetshenziswa i-Sudan Black B: Iyacasula emehlweni nasesikhumbeni, futhi ukuthintana ngokuqondile kufanele kugwenywe lapho ithintwa. Izinyathelo zokuzivikela ezifanele, njengamagilavu ​​aselabhorethri kanye nezibuko, kufanele zigqokwe lapho uphathwa noma uthintwa. Musa ukuhogela impushana noma isixazululo seSudan Black B futhi ugweme ukumunca noma ukugwinya. Izinqubo ezifanele zokusebenza kufanele zilandelwe elabhorethri futhi kufanele zisetshenziswe endaweni enomoya omuhle.
