Description

2-Cyclopentene-1-Carboxylicacid,4-Mercapto-,Methylester(9Ci) is a specialized, high-value chemical intermediate featuring a unique cyclopentene backbone functionalized with both carboxylic acid ester and thiol (mercapto) groups. This molecular architecture makes it a critical building block for synthesizing complex molecules in advanced research and development. It is primarily sought after by pharmaceutical and agrochemical R&D teams for constructing novel active ingredients and by fine chemical manufacturers for producing custom catalysts and ligands.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of novel drug candidates, particularly for central nervous system (CNS) and anti-inflammatory targets.
• Agrochemical Synthesis: Used in the creation of advanced pesticide and herbicide molecules, leveraging its reactive sites for structural diversification.
• Catalyst & Ligand Precursor: The thiol and ester functionalities make it a valuable starting material for synthesizing specialized metal-chelating ligands and organocatalysts.
• Fine Chemical Production: Employed in custom synthesis and contract manufacturing for producing high-value, low-volume specialty chemicals.
• Material Science Research: Investigated as a monomer or cross-linking agent for developing novel polymers with specific functional properties.
• Academic & Industrial R&D: A versatile tool for methodological chemistry research, including studies in asymmetric synthesis and cycloaddition reactions.
