CAS 547-58-0: Methylorange
Beschreibung:
Methylorange ist ein Azofarbstoff, der häufig als pH-Indikator in Titrationen verwendet wird, insbesondere im sauren Bereich. Seine chemische Formel ist C14H14N3NaO3S, und er erscheint als gelbes bis rotes Pulver, abhängig vom pH-Wert der Lösung. Methylorange zeigt einen deutlichen Farbwechsel von rot bei einem pH-Wert unter 3,1 zu gelb bei einem pH-Wert über 4,4, was ihn nützlich macht, um den Endpunkt von Säure-Base-Reaktionen zu bestimmen. Er ist in Wasser löslich und hat eine relativ geringe Toxizität, sollte jedoch dennoch mit Vorsicht behandelt werden. Die Verbindung ist unter normalen Bedingungen stabil, kann jedoch abgebaut werden, wenn sie starken Oxidationsmitteln oder extremen pH-Werten ausgesetzt wird. Methylorange wird auch in verschiedenen Anwendungen über die pH-Anzeige hinaus verwendet, einschließlich in Färbeprozessen und als biologischer Farbstoff. Seine einzigartigen Eigenschaften machen ihn zu einem wertvollen Werkzeug sowohl in Labor- als auch in Industrieumgebungen.

CAS:Methyl orange is a dye that is used as an indicator in acid-base titrations. It has a basic structure and can be prepared by the oxidation of para-aminobenzoic acid with hydrogen peroxide. Methyl orange has been shown to exhibit synergistic effects with other antimicrobial agents, such as phenol, methylene blue, and chlorhexidine at pH levels of 4.5 to 7.0. The optimum concentration for the matrix effect is 0.01% at pH range from 2.5 to 4.5 and 1% at pH range from 5 to 7.5. Methyl orange is activated by light with wavelengths between 300 nm and 500 nm and can be used in wastewater treatment processes where there are high levels of organic matter or radiation, such as carthamus tinctorius or zirconium oxide.Formel:C14H15N3O3S•NaReinheit:Min. 95%Farbe und Form:PowderMolekulargewicht:328.34 g/molMethyl orange, Indicator
