Amiodarone-d10 Hydrochloride is primarily used in research and development as a deuterated analog of amiodarone, a well-known antiarrhythmic medication. Its applications include:

• Pharmacokinetic Studies: It serves as an internal standard in mass spectrometry for quantifying amiodarone levels in biological samples, ensuring accuracy in drug metabolism and distribution studies.
• Drug Development: Researchers use it to investigate the metabolic pathways and stability of amiodarone, aiding in the development of improved formulations or derivatives.
• Toxicology Research: It helps assess the long-term effects and safety profile of amiodarone, particularly in understanding its accumulation in tissues and potential side effects.
• Clinical Trials: It supports the monitoring of amiodarone in patient samples during trials, ensuring precise measurement of drug concentrations for efficacy and safety evaluations.

Its deuterated structure provides enhanced analytical precision, making it a valuable tool in advancing pharmaceutical and medical research.
