Description

CAS: 845-10-3 | C15H14N3NaO2 | 291.286 g/mol

Methyl red is an indicator dye that turns red in acidic solutions. It is a pH indicator, turning red under pH 4.4, yellow over pH 6.2, and orange in between those values. It is used in microbiology in the Voges-Proskauer test to identify bacteria that produce stable acids through mixed acid fermentation of glucose. Methyl-red positive bacteria include Proteus vulgaris and Escherichia coli. Methyl-red negative bacteria include Enterobacter aerogenes and Serratia marcescens.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
El rojo de metilo es un colorante indicador que se vuelve rojo en soluciones ácidas. Es un indicador de pH, que se vuelve rojo cuando el pH es inferior a 4,4, amarillo cuando el pH es superior a 6,2 y naranja entre esos valores. Se utiliza en microbiología en la prueba Voges-Proskauer para identificar bacterias que producen ácidos estables a través de la fermentación de ácidos mixtos de glucosa. Las bacterias positivas a los rojos de metilo son Proteus vulgaris y Escherichia coli. Las bacterias negativas de metilo de rojo son Enterobacter aerogenes y Serratia marcescens.

Solubilidad
Soluble en agua (800 mg/ml a 25 °C) y ligeramente soluble en etanol a (25 °C).
