CAS 547-58-0: Orangé de méthyle
Description :
Orangé de méthyle est un colorant azoïque couramment utilisé comme indicateur de pH dans les titrations, en particulier dans la plage acide. Sa formule chimique est C14H14N3NaO3S, et il apparaît sous forme de poudre jaune à rouge, selon le pH de la solution. Orangé de méthyle présente un changement de couleur distinct de rouge à un pH inférieur à 3,1 à jaune à un pH supérieur à 4,4, ce qui le rend utile pour déterminer le point final des réactions acido-basiques. Il est soluble dans l'eau et a une toxicité relativement faible, bien qu'il doive être manipulé avec précaution. Le composé est stable dans des conditions normales, mais peut se dégrader lorsqu'il est exposé à des agents oxydants forts ou à des niveaux de pH extrêmes. Orangé de méthyle est également utilisé dans diverses applications au-delà de l'indication du pH, y compris dans les processus de teinture et comme colorant biologique. Ses propriétés uniques en font un outil précieux tant dans les laboratoires que dans les environnements industriels.

Methyl Orange
CAS :Produit contrôléApplications Methyl orange is a pH indicator dye for titrations. Dyes and metabolites.Formule :C14H14N3O3S·NaCouleur et forme :NeatMasse moléculaire :327.33Methyl orange
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.Formule :C14H15N3O3S•NaDegré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :328.34 g/molMethyl orange, Indicator
