CAS 76-60-8: Verde di bromocresolo
Descrizione:
Verde di bromocresolo è un colorante sintetico e indicatore di pH comunemente utilizzato in varie applicazioni biochimiche. È caratterizzato dalla sua capacità di cambiare colore in risposta a variazioni di pH, passando tipicamente da giallo in condizioni acide a blu in ambienti alcalini, con un intervallo di transizione di pH intorno a 3,8-5,4. Questa proprietà lo rende prezioso nelle titolazioni e come colorante biologico. Chimicamente, Verde di bromocresolo è un derivato del fenolo solfonato, e la sua struttura molecolare include atomi di bromo, che contribuiscono alle sue proprietà colorimetriche. È solubile in acqua e presenta uno spettro di assorbimento distintivo, rendendolo utile nelle analisi spettrofotometriche. Inoltre, Verde di bromocresolo è spesso impiegato in laboratori microbiologici e clinici per la rilevazione di alcuni microrganismi e nella valutazione delle concentrazioni proteiche. Sebbene generalmente considerato sicuro per l'uso in laboratorio, è importante maneggiarlo con cura, come tutte le sostanze chimiche, per evitare potenziali rischi per la salute.

CAS:Bromocresol green is a cationic surfactant that is used as a fluorescent indicator dye. It binds to proteins and can be detected with an optical sensor. Bromocresol green has been shown to react with hydrochloric acid, which may be due to the protonation of the cationic group. This reaction is reversible and depends on pH. The binding of bromocresol green to serum proteins results in a decrease in fluorescence intensity due to quenching by adsorption at the protein-protein interface. The kinetic data for this dye have been found to depend on α1-acid glycoprotein concentration.Formula:C21H14Br4O5SColore e forma:PowderPeso molecolare:698.01 g/mol
