Description

Lexiscan CAS NO 875148-45-1 is a high-purity pharmaceutical active ingredient, specifically a selective A2A adenosine receptor agonist. This compound is critical for its diagnostic utility in cardiac stress testing, offering a safe and effective alternative to traditional exercise stress for patients unable to undergo physical exertion. It is primarily required by pharmaceutical manufacturers, diagnostic imaging centers, and research institutions developing or utilizing myocardial perfusion imaging agents.

Application

• Pharmaceutical Manufacturing: As the active pharmaceutical ingredient (API) in the production of finished injectable diagnostic drugs.
• Cardiac Stress Testing: Used as a pharmacological stress agent in myocardial perfusion imaging (MPI) with single-photon emission computed tomography (SPECT).
• Diagnostic Imaging: A key component in non-invasive diagnostic procedures to assess coronary artery disease in patients who cannot exercise adequately.
• Clinical Research: Utilized in studies investigating coronary blood flow, cardiovascular physiology, and new diagnostic protocols.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in pharmaceutical analysis.
• Biochemical Research: Used as a selective tool compound in studies of adenosine receptor signaling pathways and related therapeutic areas.
