Description

S-(-)-Alprenolol is the single enantiomer of the non-selective β-adrenergic receptor antagonist, alprenolol. This high-purity chiral building block is critical for pharmaceutical research and development, particularly in the study of stereospecific drug activity and metabolism. It is primarily utilized by research institutions and pharmaceutical companies engaged in cardiovascular drug discovery, pharmacokinetic studies, and the synthesis of novel active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Key chiral synthon in the research and development of β-blocker medications.
• Biochemical Research: Used as a reference standard and tool compound in pharmacological studies of β-adrenergic receptors.
• Metabolite Studies: Employed in the investigation of stereoselective metabolism and pharmacokinetic profiles.
• Analytical Standard: Serves as a high-purity standard for HPLC, LC-MS, and other analytical methods in quality control laboratories.
• Asymmetric Synthesis: Valuable starting material or reference for developing enantioselective synthetic routes.
