Acid Orange 56 (CAS NO : 6470-20-8)

Acid Orange 56 (CAS 6408-26-0) is a specialized monoazo dye increasingly utilized in the United States within the API intermediates market for the development of diagnostic reagents and as a marker in pharmaceutical research where a Pharma/API purity 99% is required to ensure consistent bio-analytical results. CI 17055 serves as a high purity fine chemical for North American textile and leather manufacturers who are pivoting toward domestic custom synthesis services to satisfy stringent EPA and OSHA safety regulations while reducing reliance on volatile international supply chains. Benzenesulfonic acid, 3-[[4-(phenylamino)phenyl]azo]-, monosodium salt is also a critical component in industrial coatings and paper manufacturing at a General Industry purity 98%, where its high solubility and affinity for fibers make it a preferred choice for companies seeking a reliable bulk chemical supplier capable of meeting the technical demands of the American Chemical Society standards. As an established industrial chemical suppliers in the united states, we ensure dependable supply, consistent quality, and complete regulatory documentation, including CoA and TDS across all grades. Beyond supply, we support partners through the entire product lifecycle from route scouting, process and formulation development, and analytical method development to scale-up, process optimisation, and pilot-to-commercial manufacturing. Our teams also assist with GMP-compliant quality assurance, regulatory documentation, and global supply chain and logistics coordination
