Description

Clopidogrel is a potent antiplatelet agent belonging to the thienopyridine class of pharmaceuticals. This active pharmaceutical ingredient (API) is critical for the prevention of atherothrombotic events in patients with conditions such as acute coronary syndrome, recent myocardial infarction, stroke, or established peripheral arterial disease. It is essential for pharmaceutical manufacturers and research institutions developing cardiovascular medications. The compound Clopidogrel CAS NO 1319197-71-1 is supplied under stringent quality control to ensure efficacy and safety in final drug formulations.

Application

• Active Pharmaceutical Ingredient (API): Primary use in the commercial synthesis of finished dosage forms, most notably oral antiplatelet tablets.
• Cardiovascular Drug Manufacturing: Core component in medications prescribed to inhibit blood clot formation, reducing the risk of heart attack and stroke.
• Generic Drug Production: Serves as the key ingredient for manufacturers producing bioequivalent versions of branded clopidogrel medicines.
• Pharmaceutical Research & Development: Used in preclinical and clinical studies for developing new cardiovascular therapies or combination drugs.
• Formulation Development: Employed in creating various drug delivery systems, including bespoke dosage forms for specific patient populations.
• Reference Standard: High-purity grades are utilized as analytical standards in quality control laboratories for method development and validation.

Quality Control

Our Clopidogrel is manufactured and tested under a strict quality management system. Each batch is analyzed to meet high-purity standards suitable for pharmaceutical applications, with testing typically including identification, assay, impurity profile, and residual solvents. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing all test results against predefined specifications. We support compliance with cGMP, ICH Q7 guidelines, and relevant pharmacopoeial standards (USP/EP).

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and purity. Keep away from incompatible materials.
