3,4,5,6-Tetrabromophenolssulfonephthalein CAS:77172-72-6

3,4,5,6-Tetrabromophenolsulfonephthalein (TBPSPT) bụ ihe e ji agba agba nke a na-eji dị ka ihe ngosi na kemistri nyocha. Mmetụta na ojiji ya na-adaberekarị na njirimara mgbanwe agba ya.

A na-ejikarị TBPSPT eme ihe dị ka ihe ngosi acid-base n'ihi ikike ya ịgbanwe agba dabere na pH nke ngwọta ahụ. Ọ na-abụkarị ọbara ọbara na obere pH (ọnọdụ acidic) na odo odo na nnukwu pH (ọnọdụ ndị bụ isi). Mgbanwe agba a nwere ike ịba uru na ọtụtụ ojiji, dị ka titrations na mkpebi pH, ebe a ga-achọpụta njedebe nke mmeghachi omume ma ọ bụ acidity/alkalinity nke ngwọta.

Tinyere nke ahụ, ejirila TBPSPT mee ihe n'ọmụmụ ihe gbasara gburugburu ebe obibi, karịsịa maka ịchọpụta ụdị oxygen reactive (ROS). Mgbe e tinyere ya na ROS, dị ka hydroxyl radicals ma ọ bụ singlet oxygen, TBPSPT na-agbanwe agba, na-enye ihe ngosi anya nke ọnụnọ nke ụdị reactive ndị a.
