Yintoni iBromocresol Green eneCAS 76-60-8?

I-Bromocresol green iyanyibilika kancinci emanzini kwaye iyanyibilika kwi-ethanol, i-ether, i-ethyl acetate, kunye ne-benzene. Ibuthathaka kakhulu kwi-alkali, i-Bromocresol green ijika ibe nombala oluhlaza okwesibhakabhaka okhethekileyo xa idibana nezisombululo zamanzi ze-alkaline. I-Bromocresol green ingasetyenziswa njengesalathisi, ibonakale ityheli kwi-pH 3.8 kwaye iluhlaza okwesibhakabhaka kwi-pH 5.4.

Inkcazo

Izinto	Inkcazo
I-PH (ixesha lotshintsho)	3.8 (oluhlaza okwesibhakabhaka) -5.4 (oluhlaza okwesibhakabhaka)
Ubude bomda wokufunxa obuphezulu (nm) λ1 (PH 3.8) λ2 (PH 5.4)	440~445 615~618
I-coefficient yokufunxa ubunzima, L/cm · g α1（λ1PH 3.8, isampuli eyomileyo） α2（λ2PH 5.4, isampuli eyomileyo)	24~28 53~58
Uvavanyo lokuchithwa kwe-ethanol	ipasi
Intsalela evuthayo (ibalwa njenge-sulfate)	≤0.25
Ilahleko yokomisa	≤3.0

Isicelo

1. I-Bromocresol eluhlaza yiarhente yokudaya iiseli
2. Uluhlaza lweBromocresol luphawu lwe-Acid-base, i-pH itshintsha umbala ukusuka kwi-3.8 (tyheli) ukuya kwi-5.4 (luhlaza okwesibhakabhaka)
3. Ityuwa yesodiyam eluhlaza yeBromocresol isetyenziswa kakhulu ekumiseleni i-acidity kunye ne-alkalinity ngemibala. Isisombululo sesodiyam yeBromocresol green sisetyenziswa njenge-agent ye-colorimetric yokulinganisa ixabiso le-pH nge-spectrophotometry. Isetyenziswa njenge-reagent ye-chromatography yomaleko omncinci ukumisela i-aliphatic hydroxyacids kunye ne-alkaloids, kunye ne-arhente yokukhupha kunye nokwahlulahlula ukumisela i-photometric ye-quaternary ammonium cations.
