Description

Pyridine, 2-(4-Methyl-2-Oxido-1,2,3-Oxathiazolidin-3-Yl)-, (4R)- (9Ci) is a specialized chiral heterocyclic compound featuring a pyridine ring fused with a 1,2,3-oxathiazolidine oxide moiety. This unique molecular architecture makes it a valuable high-purity intermediate for the synthesis of complex active pharmaceutical ingredients (APIs) and advanced agrochemicals. It is primarily required by pharmaceutical R&D and fine chemical synthesis teams seeking to introduce specific stereochemistry and functional groups into target molecules.

Application

• Pharmaceutical Intermediate: A key chiral building block in the synthesis of novel therapeutic agents, particularly in antiviral and central nervous system (CNS) drug discovery programs.
• Agrochemical Synthesis: Used in the development of advanced, enantiomerically pure pesticides and herbicides with improved efficacy and environmental profiles.
• Asymmetric Catalysis: Serves as a precursor or ligand in catalytic systems designed for stereoselective chemical transformations.
• Chemical Research & Development: Employed in academic and industrial labs for exploring new synthetic methodologies and constructing complex molecular libraries.
• Material Science Precursor: Potential use in the synthesis of specialized ligands for metal-organic frameworks (MOFs) or functional polymers.
