CAS 493-52-7: Rosso metile

Descrizione: Rosso metile è un composto organico classificato come indicatore di pH, comunemente utilizzato in titolazioni e varie applicazioni di laboratorio. Appare come una polvere rossa a gialla, a seconda del pH della soluzione in cui si trova; passa da rosso a un pH inferiore a 4,4 a giallo a un pH superiore a 6,2. Rosso metile ha una formula molecolare di C15H15N3O2 e un peso molecolare di circa 269,3 g/mol. È solubile in alcol e leggermente solubile in acqua, rendendolo utile in vari sistemi di solventi. Il composto mostra un forte cambiamento di colore, particolarmente prezioso per determinare il punto finale delle titolazioni acido-base. Rosso metile è anche noto per la sua stabilità in condizioni normali di laboratorio, sebbene possa degradarsi se esposto a luce intensa o calore. Inoltre, ha applicazioni in microbiologia per differenziare tra alcune specie batteriche in base alla loro attività metabolica. Tuttavia, devono essere adottate precauzioni di sicurezza, poiché può essere dannoso se ingerito o inalato.
