Description

K-Strophanthin-Beta CAS NO 560-53-2 is a specific cardiac glycoside derived from the seeds of *Strophanthus kombé*. This compound is of significant interest for its potent biological activity, primarily as a reference standard and research material in the study of cardiac pharmacology and biochemistry. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and academic sectors who require high-purity biochemicals for analytical, diagnostic, and developmental purposes.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quality control and assay development of cardiac glycoside-based drugs.
• Biochemical Research: Serves as a critical tool in pharmacological studies to investigate the mechanism of action of Na+/K+-ATPase inhibition and cardiac contractility.
• Diagnostic Reagent Development: Employed in the formulation of in-vitro diagnostic (IVD) kits and assays for cardiac function testing.
• Academic & Clinical Studies: Utilized in university and hospital laboratories for fundamental research on heart failure and related cardiovascular conditions.
• API Intermediate: Acts as a key starting material or intermediate in the synthesis of more complex cardiac therapeutic agents.
