Bromocresol wobiriwira umasungunuka pang'ono m'madzi ndipo umasungunuka mu ethanol, ether, ethyl acetate, ndi benzene. Wosakhudzidwa kwambiri ndi alkali, Bromocresol wobiriwira umasintha mtundu wapadera wabuluu-wobiriwira ukakumana ndi madzi amchere a alkaline. Bromocresol wobiriwira ungagwiritsidwe ntchito ngati chizindikiro, kuwoneka wachikasu pa pH 3.8 ndi wobiriwira wabuluu pa pH 5.4.
| Zinthu | Kufotokozera |
| PH (nthawi yosinthira) | 3.8 (chikasu chobiriwira) -5.4 (buluu) |
| Kutalika kwa mayamwidwe kwakukulu (nm) λ1 (PH 3.8) λ2 (PH 5.4) | 440~445615~618 |
| Choyezera kuyamwa kwa mass, L/cm · gα1（λ1PH 3.8, chitsanzo chouma） α2（λ2PH 5.4, chitsanzo chouma) | 24~2853~58 |
| Mayeso oyezera kusungunuka kwa Ethanol | pasipoti |
| Kuwotcha zotsalira (zowerengedwa ngati sulfate) | ≤0.25 |
| Kutayika pakuuma | ≤3.0 |
1Bromocresol wobiriwirandi choyeretsera utoto wa maselo
2.Bromocresol wobiriwiraChizindikiro cha asidi-base, pH kusintha kwa mtundu kuyambira 3.8 (wachikasu) mpaka 5.4 (buluu-wobiriwira)
3. Mchere wobiriwira wa Bromocresol umagwiritsidwa ntchito kwambiri poyesa acidity ndi alkalinity. Mchere wa sodium wa Bromocresol Green umagwiritsidwa ntchito ngati colorimetric agent poyesa pH pogwiritsa ntchito spectrophotometry. Umagwiritsidwa ntchito ngati reagent pa thin layer chromatography kuti udziwe aliphatic hydroxyacids ndi alkaloids, komanso ngati chochotsera ndi kulekanitsa poyesa photometric ya quaternary ammonium cations.
