    Sodium 4‑Aminosalicylate Dihydrate (PAS‑Na) CAS 6011-12-7

    Sodium 4‑Aminosalicylate dihydrate, commonly referred to as PAS‑Na, is an aromatic amino‑salicylate sodium salt supplied in its dihydrated crystalline form. As a well‑defined organic salt, it is classified as a specialty chemical compound within regulated chemical supply chains, where precise hydration state and compositional consistency are essential. Sodium 4‑Aminosalicylate Dihydrate (CAS 6011-12-7) is handled as a discrete molecular substance in controlled industrial and research environments, with emphasis on material identification, documentation, and regulatory compliance rather than end‑use formulation.
    The material is supplied with standardized specifications and complete technical documentation, including MSDS, TDS, and COA, ensuring traceability and conformity.
