Description

Dexsotalol CAS NO 30236-32-9 is a high-purity, non-cardioselective β-adrenergic receptor antagonist (β-blocker) with class III antiarrhythmic properties. It is a critical chiral intermediate and active pharmaceutical ingredient (API) used in advanced cardiovascular research and development. This compound is essential for pharmaceutical manufacturers, research institutions, and contract development organizations focused on creating novel antiarrhythmic and antihypertensive therapies.

Application

• Primary use as an Active Pharmaceutical Ingredient (API) in antiarrhythmic drug formulations.
• Key chiral intermediate in the synthesis of advanced β-blocker pharmaceuticals.
• Reference standard for analytical method development and quality control in pharmaceutical labs.
• Biochemical research tool for studying β-adrenergic receptor mechanisms and cardiac electrophysiology.
• Preclinical and clinical research material for cardiovascular disease studies.
• Starting material for the preparation of deuterated or other isotopically labeled analogs for metabolic studies.
