o-Kresolphthalein-Komplexon

Beschreibung:

o-Kresolphthalein-Komplexon, mit der CAS-Nummer 2411-89-4, ist eine chemische Verbindung, die häufig als Chelatbildner in der analytischen Chemie verwendet wird. Sie ist besonders effektiv bei der Komplexierung von Metallionen, was sie in Titrationen und kolorimetrischen Tests wertvoll macht. Die Verbindung zeigt eine deutliche Farbänderung, wenn sie an bestimmte Metallionen wie Calcium und Magnesium bindet, was eine visuelle Erkennung und Quantifizierung ermöglicht. o-Kresolphthalein-Komplexon ist typischerweise in organischen Lösungsmitteln löslich und hat eine moderate Löslichkeit in Wasser, abhängig vom pH-Wert der Lösung. Ihre Struktur weist eine phenolische Gruppe auf, die zu ihrer Fähigkeit beiträgt, stabile Komplexe mit Metallionen zu bilden. Diese Eigenschaft macht sie in verschiedenen Anwendungen nützlich, einschließlich der Prüfung der Wasserhärte und der Bestimmung von Metallkonzentrationen in Umweltproben. Darüber hinaus ist es wichtig, diese Verbindung mit Vorsicht zu behandeln, da sie gesundheitliche Risiken darstellen kann, wenn sie eingenommen oder eingeatmet wird, und geeignete Sicherheitsmaßnahmen während ihrer Verwendung getroffen werden sollten.

Phthalein purple

CAS: 2411-89-4

Phthalein purple is a fluorescent dye that is used as a calcium indicator for clinical pathology. It has been shown to be useful in the measurement of calcium levels in human serum and plasma, as well as in other biological fluids. Phthalein purple binds to calcium ions and forms stable complexes with them. A linear calibration curve can be obtained using this dye when runx2 gene transcription is induced by polymerase chain reaction (PCR) with primers and probes. The function of this dye can be determined by measuring the amount of fluorescence emitted when it is excited at a particular wavelength. The stability of this dye can also be determined by monitoring its fluorescence intensity over time. This dye can also act as a molecular probe for the detection of osteogenic genes and metabolic disorders, such as Paget's disease or Gaucher's disease.br>
