Description

2-Pentanone, 3-Mercapto-3-Methyl- (7Ci,9Ci) CAS NO 89534-21-4 is a specialized organosulfur compound featuring a ketone and a thiol functional group on the same carbon chain. This unique bifunctional structure makes it a valuable intermediate for synthesizing complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is primarily sought by R&D chemists and process development scientists for applications requiring the introduction of a thiol-protected ketone moiety or for creating heterocyclic compounds.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), especially those containing sulfur heterocycles or thioether linkages.
• Agrochemical Synthesis: Used in the production of advanced pesticides, herbicides, and fungicides where the thiol group can act as a reactive handle.
• Flavor & Fragrance Chemistry: Serves as a precursor for sulfur-containing aroma compounds, contributing to meaty, roasted, or tropical notes.
• Polymer & Material Science: Acts as a chain-transfer agent or cross-linking monomer in the synthesis of specialty polymers and resins.
• Chemical Research & Development: A versatile reagent for exploring novel organic transformations and catalysis involving sulfur chemistry.
• Ligand Synthesis: Useful for preparing chelating ligands in coordination chemistry and catalysis.
