Description

Clopidogrel Besylate is the besylate salt form of clopidogrel, a thienopyridine-class antiplatelet agent. This high-purity active pharmaceutical ingredient (API) is critical for the formulation of medications that prevent thrombotic events such as heart attacks and strokes. It is primarily required by pharmaceutical manufacturers for the production of generic and branded antiplatelet tablets.

Application

• Pharmaceutical API: Primary use as the active ingredient in antiplatelet medications for the prevention of atherothrombotic events.
• Cardiovascular Drug Formulation: Manufacture of oral solid dosage forms (tablets) used in patients with acute coronary syndrome, recent myocardial infarction, stroke, or established peripheral arterial disease.
• Generic Drug Production: Sourcing for the development and commercial-scale production of bioequivalent generic clopidogrel products.
• Research & Development: Used in preclinical and clinical studies for developing new combination therapies or novel drug delivery systems.
• Reference Standard: Serves as a chemical reference standard in analytical laboratories for quality control and method validation.

Quality Control

Our Clopidogrel Besylate is manufactured under strict quality management systems. It is tested to meet or exceed relevant pharmacopeial standards (such as USP/EP) for pharmaceutical-grade APIs. A comprehensive Certificate of Analysis (COA) is provided with each batch, detailing purity, identity, and impurity profiles to ensure supply reliability and regulatory compliance for our global customers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture absorption.
