Freezing/Melting Point:> 300 deg C Decomposition Temperature:Not available. Methyl red is a deep red solid, almost insoluble in water, but more soluble in organic solvents, such as glacial acetic acid, hot acetone, benzene, chloroform, ethanol, formic acid, as well as lipids. It turns out different molecules have different boiling points. Methyl red is an acidic pH indicator, which contains p-dimethylaminoaeobenzene-O-carboxylic acid that quantifies the H + ion concentration in the media. What's fascinating is that the dispersion of the coloring happens all on its own with virtually no outside assistance from us. WARNING: Irritates skin and eyes, harmful if swallowed. The tables and figures below show how the boiling point changes with increasing carbon number up to C 33 for different kinds of hydrocarbons, alcohols and carboxylic acids.
