Bromocresol Green Ndi CAS 76-60-8
Bromocresol wobiriwira amasungunuka pang'ono m'madzi ndipo amasungunuka mu ethanol, ether, ethyl acetate, ndi benzene. Kuzindikira kwambiri zamchere, zobiriwira za Bromocresol zimatembenuza mtundu wapadera wabuluu wobiriwira mukakumana ndi madzi amchere amchere. Bromocresol wobiriwira angagwiritsidwe ntchito ngati chizindikiro, kuwoneka chikasu pa pH 3.8 ndi blue-green pa pH 5.4.
| Zinthu | Kufotokozera |
| PH (nthawi yosinthira) | 3.8 (yellow green) -5.4 (buluu) |
| Maximum mayamwidwe wavelength (nm) λ1 (PH 3.8) λ2 (PH 5.4) | 440-445 615-618 |
| Kuchuluka kwa mayamwidwe kokwanira, L/cm · g α1 (λ1PH 3.8, chitsanzo chouma) α2 (λ2PH 5.4, chitsanzo chouma) | 24-28 53-58 |
| Kuyesedwa kwa Ethanol | kupita |
| Kuwotcha zotsalira (zowerengedwa ngati sulphate) | ≤0.25 |
| Kutaya pakuyanika | ≤3.0 |
1.Bromocresol wobiriwira ndi Cell staining agent
2.Bromocresol wobiriwira ndi Acid-base indicator, pH mtundu kusintha range 3.8 (yellow) mpaka 5.4 (blue-green)
3.Bromocresol mchere wobiriwira wa sodium umagwiritsidwa ntchito pozindikira mtundu wa acidity ndi alkalinity. Bromocresol green's sodium salt solution imagwiritsidwa ntchito ngati colorimetric poyesa pH mtengo ndi spectrophotometry. Ntchito ngati reagent kwa woonda wosanjikiza chromatography kudziwa aliphatic hydroxyacids ndi alkaloids, ndi monga m'zigawo ndi kulekana wothandizila photometric mtima wa quaternary ammonium cations.
