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

ʻO 3,4,5,6-Tetrabromophenolsulfonephthalein (TBPSPT) kahi hui kala i hoʻohana ʻia ma ke ʻano he hōʻailona i ka kemika loiloi. ʻO kona hopena a me kāna hoʻohana ʻana e pili nui ana i kona mau waiwai hoʻololi kala.

Hoʻohana pinepine ʻia ʻo TBPSPT ma ke ʻano he hōʻailona acid-base ma muli o kona hiki ke hoʻololi i ke kala ma muli o ka pH o ka hopena. He ʻulaʻula maʻamau ia ma ka pH haʻahaʻa (nā kūlana acidic) a he melemele ma ka pH kiʻekiʻe (nā kūlana kumu). Hiki ke lilo kēia hoʻololi kala i mea pono i nā noi like ʻole, e like me nā titrations a me nā hoʻoholo pH, kahi e pono ai ke hoʻoholo ʻia ka hopena o kahi hopena a i ʻole ka acidity/alkalinity o kahi hopena.

Eia kekahi, ua hoʻohana ʻia ʻo TBPSPT i nā haʻawina nānā kaiapuni, ʻoi aku hoʻi no ka ʻike ʻana i nā ʻano oxygen reactive (ROS). Ke hōʻike ʻia i ka ROS, e like me nā radical hydroxyl a i ʻole ka oxygen singlet, loli ke kala o TBPSPT, e hāʻawi ana i kahi hōʻailona ʻike maka o ke alo o kēia mau ʻano reactive.
