Azo dyes are synthetic dyes whose molecules contain one or more azo groups—typically linked to aromatic rings—and they constitute one of the most widely used and highest-volume classes of dyes produced globally.
M-Anisidine serves as a key raw material in the synthesis of azo dyes. It provides either the diazo component or the coupling component for the dye molecule, thereby regulating the dye’s color depth and color fastness.
Highassay’s MOQ for M-Anisidine varies depending on the product grade: Industrial Grade: 25 kg; Reagent Grade: 1 kg; High-Purity Grade: 100 g.
