Description

Propionic Acid (Z)-2-Hexenyl Ester is a specialized organic ester with a distinct, fruity-green aroma profile. This compound matters as a high-value flavor and fragrance intermediate, prized for its ability to impart fresh, natural green notes reminiscent of leaves and unripe fruit. It is primarily needed by manufacturers in the flavor and fragrance industry for creating sophisticated aromas in perfumes, cosmetics, and food products, as well as by research and development chemists exploring novel synthetic pathways.

Application

• Fragrance Formulation: A key building block for creating fresh, green, and leafy top notes in fine perfumery, personal care products, and air fresheners.
• Flavor Creation: Used as a flavoring agent to impart natural green, fruity, and vegetable-like nuances in beverages, confectionery, and savory food applications.
• Cosmetic Ingredients: Serves as a fragrance component in lotions, creams, soaps, and other cosmetic formulations.
• Chemical Synthesis: Acts as a versatile intermediate or starting material in organic synthesis for pharmaceuticals and agrochemicals.
• Aroma Chemicals: A valuable raw material for the production of other, more complex aroma chemicals.
• Research & Development: Utilized in academic and industrial R&D for studying ester chemistry, olfactory receptors, and new synthetic methodologies.

Quality Control

Our Propionic Acid (Z)-2-Hexenyl Ester is produced and tested under a strict quality management system. Every batch undergoes rigorous analytical testing, including gas chromatography (GC), to ensure high purity, consistent olfactory profile, and chemical identity. Certificates of Analysis (COA) detailing purity, specific gravity, refractive index, and organoleptic properties are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 15-25°C. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep away from heat, sparks, and open flames.
