Azo dyes are organic dyes that provide stable coloration across a wide color palette due to the presence of –N=N– azo bonds in their molecular structure.
- Optical Behavior: Bright colors, broad absorption bands, and high light fastness.
- Chemical Properties: High stability with resistance to thermal and oxidative conditions.
- Applications: Chemical testing systems, industrial color indicators, and polymer and textile analyses.
- Advantages: Cost-effective, high efficiency, and easy to modify.
