Description

Benzenesulfonic Acid, 4,5-Dichloro-2-3-Methyl-1-(3-Sulfophenyl)-1H-Pyrazol-4-Ylazo-, Compd. With n-Octadecyl-1-Octadecanamine is a high-purity, complex azo dye intermediate and surfactant compound. This specialty chemical is valued for its dual functionality, combining chromophoric properties with surfactant characteristics to deliver enhanced solubility and application performance in demanding formulations. It is primarily sought by manufacturers in the textile, ink, and specialty coatings industries for producing high-grade colorants and functional additives.

Application

• Dye and Pigment Intermediate: A key precursor for synthesizing high-performance, oil-soluble azo dyes and pigments, particularly for textile printing and coloration of plastics.
• Specialty Ink Formulations: Used in the production of inks for non-porous substrates, offering improved color strength and stability.
• Functional Surfactant: Acts as a dispersing and leveling agent in coating systems due to its amphiphilic structure derived from the octadecylamine component.
• Research & Development: Serves as a valuable building block in organic synthesis for novel chromophores and surfactant molecules in academic and industrial R&D labs.
• Industrial Coatings: Imparts specific coloration and surface-active properties in specialty industrial paint and coating applications.
