Yintoni i-Bromocresol eluhlaza kunye ne-CAS 76-60-8?

I-Bromocresol eluhlaza iyanyibilika kancinane emanzini kwaye inyibilika kwi-ethanol, ether, ethyl acetate, nakwibenzene. Uchuku kakhulu kwialkali, iBromocresol eluhlaza ijika umbala okhethekileyo oluhlaza okwesibhakabhaka xa idibana nezisombululo ezinamanzi ealkaline. I-Bromocresol eluhlaza ingasetyenziswa njengesalathisi, ibonakala iphuzi kwi-pH 3.8 kunye ne-blue-green kwi-pH 5.4.

Inkcazo

Izinto	Inkcazo
PH (ithuba lotshintsho)	3.8 (luhlaza tyheli)-5.4 (bhlowu)
Ubuninzi bobude bokufunxa (nm) λ1 (PH 3.8) λ2 (PH 5.4)	440~445 615~618
I-coefficient yokufunxa ubunzima, L/cm · g α1(λ1PH 3.8,isampulu eyomileyo) α2(λ2PH 5.4,isampulu eyomileyo)	24–28 53~58
Uvavanyo lokuchithwa kwe-Ethanol	dlula
Intsalela evuthayo (ibalwe njenge sulfate)	≤0.25
Ilahleko ekomisweni	≤3.0

Isicelo

1.Bromocresol eluhlaza yi-Cell staining agent
I-2.Bromocresol eluhlaza yi-Acid-base indicator, i-pH yokutshintsha umbala uluhlu lwe-3.8 (yellow) ukuya kwi-5.4 (blue-green)
I-3.I-Bromocresol ityuwa ye-sodium eluhlaza isetyenziswa ngokuqhelekileyo kwi-colorimetric determination of acidity and alkalinity. Isisombululo setyuwa yesodium ye-Bromocresol eluhlaza sisetyenziswa njenge-agent ye-colorimetric yokulinganisa ixabiso le-pH nge-spectrophotometry. Isetyenziswa njenge-reagent yomaleko obhityileyo wechromatography ukumisela i-aliphatic hydroxyacids kunye ne-alkaloids, kwaye njenge-arhente yokutsalwa kunye nokwahlula ukumiselwa kwe-photometric ye-quaternary ammonium cations.
