Description

Chain transfer agent for radical polymerization of methacrylates. Brominating reagent.

Application

Methyl red serves as a pH indicator and versatile aryl azo dye, widely employed in analytical chemistry for titrations involving weak bases. Its stable diazo functionality enables straightforward coupling reactions with aromatic amines under mild conditions. The compound exhibits excellent bench stability, minimal solubility in nonpolar media, and facilitates easy purification—making it well-suited for use in both laboratory-scale assays and process chemistry workflows.
