Bromocresol ntsuab yaj me ntsis hauv dej thiab yaj hauv ethanol, ether, ethyl acetate, thiab benzene. Nws rhiab heev rau alkali, Bromocresol ntsuab hloov xim xiav-ntsuab tshwj xeeb thaum ntsib cov kua alkaline. Bromocresol ntsuab siv tau ua qhov qhia, tshwm daj ntawm pH 3.8 thiab xiav-ntsuab ntawm pH 5.4.
| Cov khoom | Cov Lus Qhia Tshwj Xeeb |

| Qhov siab tshaj plaws ntawm qhov nqus dej wavelength (nm) λ1 (PH 3.8) λ2（PH 5.4） | 440~445615~618 |
| Qhov nqus ntawm pawg, L/cm · gα1 (λ1PH 3.8, qauv qhuav) α2（λ2PH 5.4, qauv qhuav) | 24~2853~58 |
| Kev sim tshuaj ethanol yaj | dhau |
| Cov seem hlawv (xam li sulfate) | ≤0.25 |
| Poob thaum ziab | ≤3.0 |
1.Bromocresol ntsuabyog tus neeg sawv cev rau cov xim ntawm tes
2. Bromocresol ntsuab yog Acid-base qhia, pH xim hloov ntau yam 3.8 (daj) txog 5.4 (xiav-ntsuab)
3. Bromocresol ntsuab sodium ntsev feem ntau siv rau hauv kev txiav txim siab xim ntawm acidity thiab alkalinity. Bromocresol ntsuab sodium ntsev kua yog siv los ua tus neeg sawv cev colorimetric rau kev ntsuas pH tus nqi los ntawm spectrophotometry. Siv ua tus reagent rau nyias txheej chromatography los txiav txim siab aliphatic hydroxyacids thiab alkaloids, thiab ua tus neeg sawv cev rho tawm thiab sib cais rau kev txiav txim siab photometric ntawm quaternary ammonium cations.
