Phenylhydrazine is a reagent for synthesizing azo dyes and colorants in packaging inks, offering stable and vibrant pigmentation with chemical resistance.

Phenylhydrazine is a key reagent used in the synthesis of dyes and colorants for printing inks in packaging applications.

Phenylhydrazine, a hydrazine derivative, serves as an intermediate in the production of azo dyes and heterocyclic compounds, enabling vibrant colorants for inks used on flexible packaging films, labels, and cartons. It facilitates the formation of stable diazonium salts, contributing to durable pigmentation in flexographic and gravure printing processes.

Key features & benefits:

- Formation of stable phenylhydrazones for analytical detection of carbonyls in quality control

- Enables synthesis of indoles and azo compounds for high-color-fastness dyes

- Versatile in creating colorants resistant to light and chemical exposure in packaged goods

Typical applications:

- Synthesis of azo dyes for printing inks in flexo/gravure processes

- Inks & colorants for packaging films, foils, and paper substrates

Polymer/substrate compatibility:

- Compatible with ink formulations for PET/OPP/PE films

- Suitable for coated papers and metallized substrates in dye synthesis
