Description

2-Pentanone, 5-Mercapto- (9Ci) CAS NO 98321-74-5 is a specialized organosulfur compound featuring a ketone and a thiol functional group. This unique bifunctional structure makes it a valuable intermediate for synthesizing more complex molecules in fine chemical and pharmaceutical research. It is primarily sought after by R&D chemists and process development scientists working in advanced material science and active pharmaceutical ingredient (API) manufacturing.

Application

• Pharmaceutical Intermediate: A key building block for the synthesis of novel drug candidates, particularly those requiring thioether or sulfide linkages.
• Ligand Synthesis: Used in the preparation of specialized ligands for catalysis and metal-organic frameworks (MOFs).
• Polymer Modification: Serves as a functional monomer or cross-linking agent to introduce sulfur-containing groups into polymer chains, altering properties like adhesion or chemical resistance.
• Flavor & Fragrance Chemistry: Acts as a precursor for sulfur-containing aroma compounds, contributing to savory or roasted notes in complex flavor profiles.
• Agrochemical Research: Employed in the development of new pesticides and herbicides where the thiol moiety can enhance biological activity.
• Chemical Synthesis Reagent: Utilized in organic transformations, such as Michael additions or nucleophilic substitutions, leveraging its reactive thiol group.
