  • Applications

    Sodium (11-methoxy-7-phenyl-5-phenylimino-4,8-disulfobenzo[a]phenazin-9-yl)azanide, CAS number: 6837-46-3, is a highly water-soluble sulfonated phenazine derivative that functions primarily as a dye and colorant. In industry it is used in textile dyeing and printing inks to impart vivid hues, and in coatings and industrial inks as a stable colorant. The compound can serve as a functional dye additive in polymer and plastics formulations, contributing color together with potential interactions in the polymer matrix. In laboratory practice it is employed as an analytical dye and staining reagent for visualization or assay development. Additionally, its redox-active sulfonated phenazine structure supports use as a chemical indicator or redox mediator in electrochemical sensing and related electronic-material applications. All uses depend on formulation constraints and regulatory compliance.
