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.

CAS:<p>Methyl red is a dye that has been used in molecular biology as a measure of the activity of DNA, RNA, and protein enzymes. The methyl red test is based on the ability of the dye to undergo a color change from red to yellow as a result of an increase in pH. Methyl red reacts with dinucleotide phosphate by intramolecular hydrogen transfer and can be used to detect the presence of antimicrobial agents, such as antibiotics, which inhibit this reaction. The optimum concentration for methyl red is at 1mg/L in human serum and wastewater treatment. A Langmuir adsorption isotherm was used to determine its surface methodology. The optical sensor for methyl red is based on its fluorescence properties.<br>Methyl Red has been shown to have no significant effect on aerobic bacteria such as Aerobacter aerogenes (1).</p>Formula:C15H15N3O2Purezza:Min. 95%Colore e forma:PowderPeso molecolare:269.3 g/molMethyl Red free acid ACS
