Description

3-Hepten-2-One (CAS NO 1119-44-4) is a highly volatile, unsaturated ketone that serves as a versatile intermediate and flavor/fragrance component. Its reactive alpha,β-unsaturated carbonyl structure makes it valuable for synthesizing more complex molecules in fine chemical production. This compound is essential for manufacturers in the fragrance, flavor, and pharmaceutical intermediate sectors seeking specific organoleptic profiles or chemical building blocks.

Application

• Fragrance and Flavor Industry: Used as a key component or intermediate in the synthesis of green, fruity, and fatty aroma notes.
• Pharmaceutical Intermediates: Serves as a building block in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Agrochemical Synthesis: Employed as a precursor in the production of certain pesticides and herbicides.
• Research & Development: Utilized in organic chemistry research for studying conjugate addition reactions and other transformations.
• Polymer Chemistry: Can act as a monomer or cross-linking agent in specialty polymer formulations.

Quality Control

Our 3-Hepten-2-One is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets exacting standards for industrial and research applications. Certificates of Analysis (COA) detailing purity, physical properties, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat sources and open flame. Recommended storage temperature is 2-8°C to maximize stability and shelf life. Keep container tightly sealed when not in use to prevent evaporation and potential contamination.
