Kodi EOSIN CAS 17372-87-1 ndi chiyani?

Eosin Y yosungunuka m'madzi ndi utoto wa acidic wopangidwa ndi mankhwala womwe umalekanitsidwa kukhala ma anion osanjidwa m'madzi ndipo amamanga ndi ma cations a protein amino magulu kuti adetse cytoplasm. The cytoplasm, maselo ofiira a m'magazi, minofu, connective minofu, eosin granules, etc. ndi wothimbirira mosiyanasiyana ofiira kapena pinki, kupanga kwambiri kusiyana ndi phata buluu.

Kugwiritsa ntchito

Eosin ndi utoto wabwino wa cytoplasm. Nthawi zambiri amagwiritsidwa ntchito limodzi ndi utoto wina monga hematoxylin kapena methylene blue. Amagwiritsidwa ntchito ngati biological staining agent. EOSIN imagwiritsidwanso ntchito ngati chizindikiro cha adsorption cha kutsimikiza kwa mvula ya Br -, I -, SCN -, MoO, Ag +, ndi zina zotero. Amagwiritsidwa ntchito ngati wothandizira chromogenic wa fluorescence photometric determination of Ag +, Pb2+, Mn2+, Zn2+, etc.
