Mesalazine

Mesalazine (CAS 89-57-6), also known as mesalamine and 5-aminosalicylic acid (5-ASA), is an aminosalicylate compound used as a pharmaceutical intermediate and functional ingredient in personal care formulations. It carries no assigned E-code and is identified under EC 201-919-1 with HS code 29225000.

In pharmaceutical manufacturing, mesalazine serves as the active substance in anti-inflammatory drug products targeting intestinal conditions, functioning by inhibiting prostaglandin synthesis locally in mucosal tissue. In cosmetic formulations, it acts as a UV absorber and skin conditioner, where its phenolic structure enables absorption of UV radiation and interaction with skin surface proteins.

Mesalazine is supplied as off-white crystals meeting Ph.Eur. monograph specifications, with REACH compliance documentation available for EU procurement. Standard packaging formats suit both laboratory-scale and bulk industrial quantities. Buyers should confirm grade suitability against their specific pharmaceutical or cosmetic application requirements prior to ordering.
