Rojo de metilo

Descripción:
Rojo de metilo es un compuesto orgánico clasificado como un indicador de pH, comúnmente utilizado en titulaciones y diversas aplicaciones de laboratorio. Aparece como un polvo rojo a amarillo, dependiendo del pH de la solución en la que se encuentre; transita de rojo a un pH inferior a 4.4 a amarillo a un pH superior a 6.2. Rojo de metilo tiene una fórmula molecular de C15H15N3O2 y un peso molecular de aproximadamente 269.3 g/mol. Es soluble en alcohol y ligeramente soluble en agua, lo que lo hace útil en varios sistemas de disolventes. El compuesto exhibe un fuerte cambio de color, lo que es particularmente valioso para determinar el punto final de las titulaciones ácido-base. Rojo de metilo también es conocido por su estabilidad en condiciones normales de laboratorio, aunque puede degradarse cuando se expone a luz intensa o calor. Además, tiene aplicaciones en microbiología para diferenciar entre ciertas especies bacterianas según su actividad metabólica. Sin embargo, se deben tomar precauciones de seguridad, ya que puede ser perjudicial si se ingiere o inhala.

  • Methyl red

    CAS:

    Methyl red is a dye that has been used in molecular biology as a measure of the activity of DNA, RNA, and protein enzymes. The methyl red test is based on the ability of the dye to undergo a color change from red to yellow as a result of an increase in pH. Methyl red reacts with dinucleotide phosphate by intramolecular hydrogen transfer and can be used to detect the presence of antimicrobial agents, such as antibiotics, which inhibit this reaction. The optimum concentration for methyl red is at 1mg/L in human serum and wastewater treatment. A Langmuir adsorption isotherm was used to determine its surface methodology. The optical sensor for methyl red is based on its fluorescence properties.
    Methyl Red has been shown to have no significant effect on aerobic bacteria such as Aerobacter aerogenes (1).
