:Methyl orange
Description:
Methyl orange is an azo dye commonly used as a pH indicator in titrations, particularly in the acidic range. Its chemical formula is C14H14N3NaO3S, and it appears as a yellow to red powder, depending on the pH of the solution. Methyl orange exhibits a distinct color change from red at a pH below 3.1 to yellow at a pH above 4.4, making it useful for determining the endpoint of acid-base reactions. It is soluble in water and has a relatively low toxicity, although it should still be handled with care. The compound is stable under normal conditions but can degrade when exposed to strong oxidizing agents or extreme pH levels. Methyl orange is also utilized in various applications beyond pH indication, including in dyeing processes and as a biological stain. Its unique properties make it a valuable tool in both laboratory and industrial settings.

CAS:<p>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.</p>Formula:C14H15N3O3S•NaPurity:Min. 95%Color and Shape:PowderMolecular weight:328.34 g/molMethyl Orange
