Vermelho de metila

Descrição:

Vermelho de metila é um composto orgânico classificado como um indicador de pH, comumente utilizado em titulações e várias aplicações de laboratório. Aparece como um pó vermelho a amarelo, dependendo do pH da solução em que se encontra; transita de vermelho em um pH abaixo de 4,4 para amarelo em um pH acima de 6,2. Vermelho de metila tem uma fórmula molecular de C15H15N3O2 e um peso molecular de aproximadamente 269,3 g/mol. É solúvel em álcool e ligeiramente solúvel em água, tornando-o útil em vários sistemas de solventes. O composto exibe uma forte mudança de cor, o que é particularmente valioso para determinar o ponto final das titulações ácido-base. Vermelho de metila também é conhecido por sua estabilidade em condições normais de laboratório, embora possa se degradar quando exposto a luz intensa ou calor. Além disso, tem aplicações em microbiologia para diferenciar entre certas espécies bacterianas com base em sua atividade metabólica. No entanto, devem ser tomadas precauções de segurança, pois pode ser prejudicial se ingerido ou inalado.

Methyl red

CAS: 493-52-7

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).
