Iyini i-Bromocresol Purple CAS 115-40-2?

I-Bromocresol Purple ayincibiliki emanzini, incibilika ku-ethanol futhi ibonakala iphuzi, incibilika ku-sodium hydroxide encibilikisiwe kanye nezixazululo ze-sodium carbonate encibilikisiwe futhi ibonakala ibomvu onsomi, inephuzu lokuncibilika elingu-241-242 ℃. Ukusetshenziswa okuyinhloko kwe-bromocresol violet kuyinkomba ye-acid-base kanye nenkomba ye-titration engeyona emanzi.

Isicelo

Isikhombisi se-Bromocresol Purple acid-base, esisetshenziselwa ukuhlaziywa kwe-chromatographic kanye ne-titration engeyona yamanzi. Ububanzi bokushintsha kombala be-PH: 5.2 (ophuzi) -6.8 (onsomi). Isikhombisi sokufakwa komswakama. Izinga langaphakathi le-chromatography ye-amino acid. I-titration kasawoti wesiliva we-thiocyanate. Ukuna kwe-serum proteins kusetshenziswa i-spectrophotometry.
