Rosso Cresolo

Descrizione:

Rosso Cresolo è un composto organico comunemente usato come indicatore di pH in varie applicazioni chimiche. È un membro della famiglia dei fenoli ed è caratterizzato dalla sua capacità di cambiare colore a seconda del pH della soluzione in cui si trova, passando tipicamente dal giallo in condizioni acide al rosso in ambienti più alcalini. Il composto è solubile in acqua e in solventi organici, rendendolo versatile per l'uso in laboratorio. Rosso Cresolo ha una formula molecolare che riflette la sua struttura, che include un gruppo fenolico e un gruppo acido solfonico, contribuendo alle sue proprietà acide. Viene spesso utilizzato nella ricerca biologica e chimica per monitorare i cambiamenti di pH negli esperimenti, così come in varie applicazioni industriali. Devono essere considerate le questioni di sicurezza, poiché Rosso Cresolo può essere dannoso se ingerito o inalato, e devono essere seguite le procedure di manipolazione appropriate. In generale, Rosso Cresolo è uno strumento prezioso nella chimica analitica per le sue affidabili proprietà di indicatore di pH.

Cresol red

CAS: 1733-12-6

Cresol red is a weak diacidic molecule and an anionic dye largely used in genetic and biochemical studies. Cresol red is commonly used to measure the pH of aqueous solutions also from environmental samples, e.g. seawater (Byrne, 1989). Cresol red shows an increased protonation in acidic water-based solutions at low temperatures (Heger, 2006). Cresol red can be used to introduce pH-sensing features to sensing materials, such as, optical fibres or nanoparticles (Islam, 2021).
