Description

Disopyramide is a class IA antiarrhythmic agent, primarily used for the management of cardiac arrhythmias. This high-purity active pharmaceutical ingredient (API) is critical for ensuring the efficacy and safety of finished pharmaceutical formulations. It is essential for manufacturers in the pharmaceutical industry developing and producing antiarrhythmic medications. Disopyramide CAS NO 3737-09-5 is supplied to meet the stringent requirements of global pharmacopeial standards.

Application

• Pharmaceutical Active Ingredient (API): Primary use as the key therapeutic component in antiarrhythmic drug formulations.
• Ventricular Arrhythmia Treatment: Used in medications designed to treat and prevent life-threatening ventricular tachycardia and fibrillation.
• Supraventricular Arrhythmia Management: Employed in drugs for controlling atrial fibrillation and flutter.
• Generic Drug Manufacturing: Serves as the core API for producing generic versions of branded antiarrhythmic drugs.
• Clinical Research & Development: Utilized in preclinical and clinical studies for developing new cardiovascular therapies.
• Reference Standard: Can be used as a high-purity standard in analytical laboratories for quality control testing.

Quality Control

Our Disopyramide is manufactured under strict quality management systems. Each batch is tested to ensure compliance with major pharmacopeial standards such as USP and EP. A comprehensive Certificate of Analysis (COA) is provided, detailing results for identity, purity, assay, and specified impurities. We are committed to supply chain transparency and regulatory support for global market submissions.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
