Description

2-Oxazolidinone,4-Cyclopentyl-,(4R)-(9Ci) is a high-value chiral building block and pharmaceutical intermediate characterized by its specific stereochemistry at the 4-position. This compound matters for its role in the synthesis of complex molecules, particularly in medicinal chemistry where the (4R) configuration is critical for biological activity and enantiomeric purity. It is primarily needed by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), especially those targeting infectious diseases or central nervous system disorders.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of new drug candidates, particularly for antibiotics and CNS-active compounds.
• Asymmetric Synthesis: Used as a building block in stereoselective organic synthesis to introduce the cyclopentyl-oxazolidinone moiety.
• Medicinal Chemistry Research: Employed in structure-activity relationship (SAR) studies and lead optimization processes within drug discovery programs.
• Reference Standard: Serves as an analytical standard for quality control and method development in pharmaceutical analysis.
• Chemical Biology Probes: Utilized in the design and synthesis of molecular probes for studying biological targets and pathways.
