MethylRed

(493-52-7)
As indicator in 0.1% alcoholic solution; pH:4.4 red, 6.2 yellow.Used for titrating NH3, weak organic bases, e.g., alkaloids; not suitable for organic acids, except oxalic and picric acid.Methyl red is easily reduced, thereby losing its color, and readings should be made promptly.It is gradually being replaced by sulfonphthalein indicators, such as bromcresol green, which are more stable and exhibit a sharper change in color.
