Description

2-Propanone, 1-(Ethenylthio)- (9Ci) is a specialized organosulfur compound featuring a thioether-linked vinyl group and a ketone functional group. This unique molecular architecture makes it a valuable chemical intermediate for synthesizing more complex molecules, particularly in fine chemical and pharmaceutical research. It is primarily sought by R&D chemists and process development teams in the agrochemical, pharmaceutical, and specialty polymer industries for constructing novel sulfur-containing compounds.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel drug candidates, especially those requiring a vinyl sulfide moiety for further functionalization or as a pharmacophore.
• Agrochemical Synthesis: Used in the research and development of new pesticides, herbicides, and fungicides where the sulfur atom enhances biological activity or environmental degradation profiles.
• Polymer & Material Science: Acts as a monomer or co-monomer precursor for developing specialty polymers with unique properties, such as modified adhesion, refractive index, or chemical resistance.
• Ligand & Catalyst Development: Employed in organometallic chemistry to create novel sulfur-based ligands for catalytic systems used in cross-coupling and other organic transformations.
• Flavor & Fragrance Chemistry: Utilized as an intermediate for synthesizing complex sulfur-containing aroma compounds that contribute to savory, roasted, or tropical notes.
• Organic Synthesis Reagent: Functions as a versatile reagent in academic and industrial laboratories for introducing the 1-(ethenylthio)acetone unit into target molecules via addition or polymerization reactions.

Quality Control

Our 2-Propanone, 1-(Ethenylthio)- is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC/HPLC for purity and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, keep away from heat, sparks, open flames, and strong oxidizing agents. Minimize exposure to air and moisture during handling.
