Description

(R)-Methixene CAS NO 115511-21-2 is a high-purity, single-enantiomer chiral compound of significant interest in advanced pharmaceutical research and development. This specific stereoisomer is valued for its precise biological activity and serves as a critical intermediate or active pharmaceutical ingredient (API) in the synthesis of targeted therapeutics. It is primarily utilized by pharmaceutical companies, contract research organizations (CROs), and academic institutions engaged in the development of new drugs, particularly those targeting neurological and receptor-specific pathways.

Application

• Pharmaceutical Intermediate: A key chiral building block in the synthesis of novel active pharmaceutical ingredients (APIs).
• Neurological Research: Used in preclinical studies for investigating compounds with potential effects on the central nervous system.
• Chiral Catalyst or Ligand: May serve as a precursor or component in asymmetric synthesis for producing other enantiomerically pure molecules.
• Reference Standard: Employed as a high-purity analytical standard for method development, validation, and quality control in pharmaceutical analysis.
• Metabolite Studies: Utilized in pharmacological and toxicological research to study drug metabolism pathways.
