Bromocresol Purple CAS 115-40-2
Bromocresol Purple ndi yosasungunuka m'madzi, imasungunuka mu ethanol ndipo imawoneka yachikasu, imasungunuka mu sodium hydroxide yosungunuka ndi kusungunula sodium carbonate solutions ndipo imawoneka yofiirira, yokhala ndi malo osungunuka a 241-242 ℃. Kugwiritsiridwa ntchito kwakukulu kwa bromocresol violet ndi chizindikiro cha acid-base komanso chizindikiro chosakhala chamadzimadzi.
