Description

Sulfaclozine Sodium is a sodium salt derivative of the sulfonamide antibiotic sulfaclozine, designed for enhanced solubility and bioavailability. This compound is valued for its potent antibacterial and anticoccidial properties, making it a critical active pharmaceutical ingredient (API) in veterinary medicine. It is primarily utilized by manufacturers in the animal health sector for the formulation of therapeutic and prophylactic treatments.

Application

• Primary active ingredient in veterinary anticoccidial preparations for poultry and livestock.
• Formulation of water-soluble powders and medicated feeds for herd-level treatment.
• Used in the production of injectable solutions for targeted therapeutic intervention.
• Manufacturing of oral suspensions and boluses for ruminants.
• Research and development of new veterinary pharmaceutical combinations.
• Intermediate in the synthesis of more complex veterinary drug formulations.
