CAS 76-60-8: Bromkresolgrün
Beschreibung:
Bromkresolgrün ist ein synthetischer Farbstoff und pH-Indikator, der häufig in verschiedenen biochemischen Anwendungen verwendet wird. Er zeichnet sich durch seine Fähigkeit aus, die Farbe als Reaktion auf pH-Änderungen zu ändern, wobei er typischerweise von Gelb in sauren Bedingungen zu Blau in alkalischen Umgebungen wechselt, mit einem pH-Übergangsbereich von etwa 3,8 bis 5,4. Diese Eigenschaft macht ihn wertvoll bei Titrationen und als biologischer Farbstoff. Chemisch gesehen ist Bromkresolgrün ein sulfoniertes Phenolderivat, und seine molekulare Struktur umfasst Bromatome, die zu seinen kolorimetrischen Eigenschaften beitragen. Er ist in Wasser löslich und weist ein ausgeprägtes Absorptionsspektrum auf, was ihn nützlich für spektrophotometrische Analysen macht. Darüber hinaus wird Bromkresolgrün häufig in mikrobiologischen und klinischen Laboren zur Erkennung bestimmter Mikroorganismen und zur Bewertung von Proteinkonzentrationen eingesetzt. Obwohl er im Allgemeinen als sicher für die Laboranwendung gilt, ist es wichtig, ihn mit Vorsicht zu behandeln, wie alle chemischen Substanzen, um potenzielle Gesundheitsrisiken zu vermeiden.

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.Formel:C21H14Br4O5SFarbe und Form:PowderMolekulargewicht:698.01 g/mol
