Kuyini iBromocresol Green ene-CAS 76-60-8?

I-Bromocresol green incibilika kancane emanzini futhi incibilika ku-ethanol, i-ether, i-ethyl acetate, kanye ne-benzene. Izwela kakhulu kuma-alkali, i-Bromocresol green iphenduka umbala okhethekile oluhlaza okwesibhakabhaka uma ihlangana nezixazululo zamanzi ze-alkaline. I-Bromocresol green ingasetshenziswa njengesibonakaliso, ibonakale iphuzi ku-pH 3.8 kanye noluhlaza okwesibhakabhaka ku-pH 5.4.

Imininingwane

Izinto	Imininingwane
I-PH (isikhawu sokuguquka)	3.8 (oluhlaza okotshani okuphuzi) -5.4 (oluhlaza okwesibhakabhaka)
Ububanzi obukhulu bokumuncwa (nm) λ1（PH 3.8） λ2（PH 5.4）	440~445 615~618
Isilinganiso sokumuncwa kwesisindo, L/cm · g isampula eyomile engu-α1（λ1PH 3.8） α2（λ2PH 5.4, isampula eyomile)	24~28 53~58
Ukuhlolwa kokuncibilika kwe-ethanol	iphasi
Izinsalela ezivuthayo (ezibalwa njenge-sulfate)	≤0.25

Isicelo

1. I-Bromocresol eluhlaza iyi-ejenti yokudaya amaseli
2. Uhlaza lwe-Bromocresol luyinkomba yesisekelo se-Acid, ububanzi bokushintsha kombala we-pH busukela ku-3.8 (ophuzi) kuya ku-5.4 (oluhlaza okwesibhakabhaka)
3. Usawoti we-sodium oluhlaza we-Bromocresol uvame ukusetshenziswa ekunqumeni i-acidity kanye ne-alkalinity ngemibala. Isixazululo se-sodium salt sika-Bromocresol green sisetshenziswa njenge-ejenti ye-colorimetric yokulinganisa inani le-pH nge-spectrophotometry. Sisetshenziswa njenge-reagent ye-chromatography yengqimba encane ukunquma ama-hydroxyacids e-aliphatic kanye nama-alkaloids, kanye ne-ejenti yokukhipha nokuhlukanisa yokunquma i-photometric yama-quaternary ammonium cations.
