Quinidine
Quinidine (CAS 56-54-2) is a naturally occurring cinchona alkaloid with the molecular formula C20H24N2O2 and a molar mass of 324.42 g/mol. The dextrorotatory diastereomer of quinine, it is a well-characterised bioactive small molecule and a Class Ia antiarrhythmic that acts as a cardiac sodium-channel blocker. In research and synthesis it serves as a chiral ligand and organocatalyst. Tech Serve Solutions supplies Quinidine in the anhydrous form for laboratory, research and industrial use.
