Description : N-(2-((Phenylcarbamoyl)amino)phenyl)benzenesulfonamide (CAS No: 168641-27-2), commercially recognized as a leading non-phenol color developer (Pergafast 201 class), is undergoing a dramatic structural transition from a niche specialty additive to the dominant, eco-compliant color developer across the global thermal paper, advanced ink-free printing, and specialty dye coating industries. Driven by stringent international regulatory bans on legacy bisphenol-based developers (such as Bisphenol A / BPA and Bisphenol S / BPS), paper coaters and thermal media manufacturers are rapidly adopting this non-bisphenol sulfonylurea matrix. Serving as a high-performance color developer, N-(2-((Phenylcarbamoyl)amino)phenyl)benzenesulfonamide reacts cleanly with leuco dyes upon thermal activation to produce deep, high-contrast, and fade-resistant image formation without estrogenic or endocrine-disrupting hazards. Its exceptional thermal stability and background whiteness make it indispensable for global point-of-sale (POS) receipts, self-adhesive shipping labels, medical imaging paper, and next-generation ink-free thermal printing media. As a globally established supplier of N-(2-((Phenylcarbamoyl)amino)phenyl)benzenesulfonamide, we ensure dependable bulk supply, strict particle-size management, and complete technical dossiers, including CoA and TDS across all industrial grades. Beyond supply, we support international partners through the entire product lifecycle, from thermal slurry formulation and particle wet-milling optimisation to full commercial coating runs, ensuring robust quality assurance, global regulatory alignment, and secure cross-border supply chain logistics.
