Iyini i-Bromocresol Green Nge-CAS 76-60-8?

I-Bromocresol eluhlaza iyancibilika kancane emanzini futhi inyibilika ku-ethanol, ether, ethyl acetate, ne-benzene. Izwela kakhulu i-alkali, i-Bromocresol eluhlaza ishintsha umbala okhethekile oluhlaza okwesibhakabhaka uma ihlangabezana nezixazululo ezinamanzi ane-alkali. I-Bromocresol eluhlaza ingasetshenziswa njengenkomba, ebonakala iphuzi ku-pH 3.8 kanye nohlaza okwesibhakabhaka ku-pH 5.4.

Ukucaciswa

Izinto	Ukucaciswa
PH (isikhathi soguquko)	3.8 (okuluhlaza okuphuzi)-5.4 (okuluhlaza okwesibhakabhaka)
Ubukhulu be-wavelength bokumuncwa (nm) λ1 (PH 3.8) λ2 (PH 5.4)	440 ~ 445 615~618
I-coefficient yokumunca ngobuningi, L/cm · g α1(λ1PH 3.8,isampula elomile) α2(λ2PH 5.4,isampula elomile)	24-28 53-58
Ukuhlolwa kokuqedwa kwe-Ethanol	dlula
Izinsalela ezivuthayo (zibalwa njenge-sulfate)	≤0.25
Ukulahlekelwa ekomisweni	≤3.0

Isicelo

1.I-Bromocresol eluhlaza i-Cell staining agent
2.I-Bromocresol eluhlaza iyinkomba ye-Acid-base, i-pH yokushintsha kombala ibanga 3.8 (ophuzi) ukuya ku-5.4 (blue-green)
3.I-Bromocresol green sodium usawoti uvame ukusetshenziswa ekunqumeni umbala we-acidity kanye ne-alkalinity. Isixazululo sikasawoti we-sodium ye-Bromocresol eluhlaza sisetshenziswa njenge-ejenti ye-colorimetric yokukala inani le-pH nge-spectrophotometry. Isetshenziswa njenge-reagent ye-chromatography yongqimba oluncane ukuze kunqunywe ama-aliphatic hydroxyacids nama-alkaloid, nanjenge-ejenti yokukhipha nokuhlukanisa ukuze kunqunywe i-photometric ye-quaternary ammonium cations.
