Methyl Red Free AcidMethyl Red Free Acid CAS: 493 52 7 MF: C15H15N3O2 MW: 269. 3, Buy now for reliable and Reproducible results from Tristains indicators at Chemical World. Methyl Red Free Acid (CAS No. 493 52 7) is a red crystalline solid or powder that is usually employed as a pH indicator in laboratory analysis. It shows a sharp color change at pH 5. 5 and therefore it is ideal in the measurement of acid and bases. Free acid form is insoluble in water and strongly

thus producing a stable fluorescence and reliable results

Selectivity: High selectivity of the staining towards mucopolysaccharides and tissue elements

Whether you are buying small quantities to be used in a single project or buying in bulk so you can do continuous testing
