Lub caij no, peb nkag mus rau ntau lub chaw tsim khoom, ua ke nrog peb cov kev tswj hwm zoo, kuj ua kom peb tuaj yeem ua tiav koj cov kev xav tau ntawm tus nqi zoo tshaj plaws, tsis hais qhov kev txiav txim loj.
Bromocresol ntsuab yog me ntsis soluble hauv dej thiab soluble hauv ethanol, ether, ethyl acetate, thiab benzene. rhiab heev rau alkali, Bromocresol ntsuab hloov xim xiav-ntsuab ntsuab tshwj xeeb thaum ntsib alkaline aqueous daws. Bromocresol ntsuab tuaj yeem siv los ua qhov taw qhia, tshwm daj ntawm pH 3.8 thiab xiav-ntsuab ntawm pH 5.4.

1.Bromocresol ntsuabyog Cell staining agent
2.Bromocresol ntsuab yog Acid-base qhia, pH xim hloov ntau yam 3.8 (daj) rau 5.4 (xiav-ntsuab)
3.Bromocresol ntsuab sodium ntsev yog feem ntau siv nyob rau hauv colorimetric txiav txim siab ntawm acidity thiab alkalinity. Bromocresol Green's sodium ntsev tov yog siv los ua tus neeg saib xyuas colorimetric rau ntsuas pH tus nqi los ntawm spectrophotometric. Siv los ua ib qho reagent rau nyias txheej chromatography los txiav txim aliphatic hydroxyacids thiab alkaloids, thiab raws li ib tug extraction thiab sib cais tus neeg saib xyuas rau photometric txiav txim ntawm quaternary ammonium cations.
