Description

Clorsulon is a potent anthelmintic agent belonging to the sulfonamide class, specifically developed for veterinary use. Its primary value lies in its high efficacy against major parasitic trematodes, particularly liver flukes (Fasciola hepatica), which cause significant economic losses in livestock production. This makes it an essential component in the formulation of veterinary pharmaceuticals for the treatment and control of parasitic infections in cattle, sheep, and other ruminants. Its reliable performance supports animal health and farm productivity on a global scale.

Application

• Veterinary Anthelmintic Formulations: Primary active ingredient in injectable solutions, drenches, and boluses for the treatment of fascioliasis (liver fluke infection).
• Livestock Parasite Control Programs: Critical for integrated parasite management (IPM) in dairy and beef cattle, sheep, and goat farming operations.
• Pharmaceutical Intermediates: Used in the synthesis of more complex veterinary drug compounds and combination therapies.
• Animal Health Research: Serves as a reference standard and active component in preclinical and clinical studies for new antiparasitic agents.
• Feed Additive Premixes: Incorporated into medicated feeds for prophylactic control of parasitic infestations in herds.
• Generic Veterinary Drug Manufacturing: Sourced by API manufacturers producing generic versions of established flukicide treatments.

Quality Control

Our Clorsulon is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Quality assurance includes comprehensive testing against established pharmacopeial standards where applicable. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting critical parameters such as identity, purity, and impurity profiles. We are committed to supplying material that meets the stringent requirements of the veterinary pharmaceutical industry.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
