Porpora di bromocresolo

Descrizione:

Porpora di bromocresolo è un colorante sintetico e indicatore di pH comunemente utilizzato in varie applicazioni biochimiche. Appare come un solido che varia dal giallo al viola, a seconda del pH della soluzione in cui si trova; passa dal giallo in condizioni acide al viola in ambienti alcalini, tipicamente all'interno di un intervallo di pH di circa 6,0-7,6. Il composto è solubile in acqua e alcol, rendendolo versatile per l'uso in laboratorio. La sua struttura chimica include un cresolo bromurato, che contribuisce alle sue proprietà di cambiamento di colore. Porpora di bromocresolo è spesso utilizzato in mezzi microbiologici, così come in titolazioni e altri procedimenti analitici per monitorare i cambiamenti di pH. Inoltre, è importante maneggiare questa sostanza con cura, poiché può essere un irritante per la pelle e gli occhi. In generale, Porpora di bromocresolo serve come uno strumento prezioso sia in contesti educativi che di ricerca, fornendo indizi visivi per i livelli di pH in vari processi chimici e biologici.
