Description

2-Pentanone, 4-(Methylthio)- (9Ci) is a specialized sulfur-containing ketone with the CAS registry number 143764-28-7. This compound serves as a valuable intermediate and building block in advanced organic synthesis, particularly for introducing functionalized alkylthio groups. It is essential for research and development chemists and process engineers in the pharmaceutical, agrochemical, and material science industries who require high-purity, structurally defined synthons.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), especially those containing sulfur heterocycles or thioether linkages.
• Agrochemical Synthesis: Used in the development and production of herbicides, fungicides, and insecticides where the methylthio-pentanone moiety contributes to biological activity.
• Flavor & Fragrance Ingredient: Acts as a potential intermediate for creating sulfur-containing aroma compounds that contribute to savory, meaty, or tropical notes.
• Material Science Research: Employed in the development of specialty polymers, ligands for catalysis, and organic electronic materials due to its reactive ketone and thioether functional groups.
• Chemical Research & Development: Serves as a versatile building block in organic chemistry for Michael additions, alkylation reactions, and the preparation of more complex sulfur derivatives.
