1.Bromocresol ntsuabyog Cell staining agent
2.Bromocresol ntsuabyog Acid-base indicator, 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 xim rau kev 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.
