Description

Olsalazine is a pharmaceutical active ingredient belonging to the class of aminosalicylates. This compound is a dimer of 5-aminosalicylic acid (5-ASA), designed for targeted delivery in the lower gastrointestinal tract. It is primarily utilized in the formulation of prescription medications for the management of inflammatory bowel diseases. Industries involved in advanced pharmaceutical synthesis and generic drug manufacturing require a reliable supply of high-purity Olsalazine CAS NO 15722-48-2 to ensure product efficacy and regulatory compliance.

Application

• Active Pharmaceutical Ingredient (API): Core component in the manufacture of prescription drugs for ulcerative colitis.
• Pharmaceutical Intermediates: Serves as a key building block in sophisticated synthetic routes for gastrointestinal therapeutics.
• Clinical Research Materials: Used in preclinical and clinical studies for developing new IBD treatments or novel drug delivery systems.
• Reference Standard: Employed in analytical laboratories for quality control, method development, and regulatory testing of finished drug products.
• Specialty Chemical Synthesis: Potential starting material for synthesizing derivatives with modified pharmacological properties.
