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

I-Bromocresol Purple ayincibiliki emanzini, iyancibilika ku-ethanol futhi ibonakala iphuzi, inyibilika ku-dilute sodium hydroxide futhi ihlanza izixazululo ze-sodium carbonate futhi ibonakala ibomvu nsomi, nendawo yokuncibilika engu-241-242 ℃. Ukusetshenziswa okuyinhloko kwe-bromocresol violet kuyinkomba ye-acid-base kanye nenkomba ye-titration engeyona amanzi.
