Bromthymolblau

Beschreibung:

Bromthymolblau ist ein pH-Indikator, der häufig in verschiedenen chemischen und biologischen Anwendungen verwendet wird. Es handelt sich um einen synthetischen Farbstoff, der je nach Säuregehalt oder Alkalität einer Lösung eine deutliche Farbänderung zeigt. Unter sauren Bedingungen erscheint er gelb, während er unter neutralen bis leicht basischen Bedingungen grün wird und in stärker alkalischen Umgebungen blau wird. Diese Eigenschaft macht ihn nützlich zur Überwachung von pH-Änderungen bei Titrationen und biologischen Experimenten. Die Verbindung hat eine chemische Formel von C27H28Br2O5S und ein Molekulargewicht von etwa 624,4 g/mol. Bromthymolblau ist in Alkohol löslich und leicht in Wasser löslich, was seine Verwendung in bestimmten wässrigen Anwendungen einschränken kann. Es wird häufig in Laborumgebungen eingesetzt, insbesondere in der Mikrobiologie und Biochemie, um den pH-Wert von Kulturmedien zu bewerten. Darüber hinaus ist es ungiftig und sicher für den Einsatz in Bildungseinrichtungen, was es zu einer beliebten Wahl für Demonstrationen und Experimente in der Säure-Base-Chemie macht.
