:Rosso Congo
Descrizione:
Rosso Congo è un colorante sintetico appartenente alla famiglia dei coloranti azoici, caratterizzato dal suo vibrante colore rosso. La sua formula chimica è C32H22N6Na2O6S2, ed è noto per la sua capacità di legarsi alle proteine, rendendolo utile in varie applicazioni biologiche. Rosso Congo presenta una proprietà unica di cambiare colore a seconda del pH della soluzione, apparendo rosso in condizioni acide e blu in ambienti alcalini, un fenomeno noto come indicatore di pH. È comunemente usato in istologia per colorare i depositi di amiloide nei tessuti, aiutando nella diagnosi di malattie come l'Alzheimer. Inoltre, Rosso Congo è stato impiegato nella tintura tessile e come colorante biologico. Tuttavia, è importante notare che Rosso Congo è stato associato a potenziali rischi per la salute, inclusa la tossicità e la cancerogenicità, portando a un controllo normativo in alcune applicazioni. Dovrebbero essere adottate misure di sicurezza adeguate quando si maneggia questo composto in ambienti di laboratorio o industriali.

CAS:<p>Direct Red 28 is a dye that can be used in wastewater treatment. It can be adsorbed onto activated sludge, which reduces the amount of sludge needing to be treated. Direct Red 28 reacts with hydrogen peroxide to form a fluorescent derivative that has antimicrobial properties. Direct Red 28 also has been shown to have an effect on the enzyme activities of kidney bean extract and to inhibit the growth of bacteria in model systems. This dye is not toxic for body formation. However, it can react with potassium dichromate and hl-60 cells, which may lead to side effects such as skin irritation.</p>Formula:C32H24N6O6S2·2NaPurezza:Min. 95%Colore e forma:Red PowderPeso molecolare:698.68 g/molCongo Red ACS, 75%
