Description

Propionic Acid trans-2-Hexen-1-Yl Ester is a specialized flavor and fragrance ester derived from propionic acid and a hexenol. This compound is valued for its unique organoleptic properties, offering a fruity, green, and slightly fatty aroma profile essential for creating complex scent and taste formulations. It is a critical ingredient for flavorists and perfumers seeking to replicate or enhance natural fruit notes, particularly in apple, pear, and tropical fruit accords.

Application

• Flavor & Fragrance Manufacturing: A key building block for creating and enhancing fruity, green, and fresh top notes in fine fragrances, personal care products, and air fresheners.
• Food & Beverage Flavoring: Used as a synthetic flavoring agent to impart natural-tasting apple, pear, melon, and unripe fruit nuances to beverages, confectionery, and dairy products.
• Aroma Chemical Synthesis: Serves as a versatile intermediate in the synthesis of more complex aroma chemicals and specialty esters.
• Cosmetic & Personal Care: Incorporated into lotions, soaps, and shampoos to provide a fresh, natural fragrance character.
• Household Products: Utilized in detergents and cleaning agents to deliver a pleasant, fruity-fresh scent profile.

Quality Control

Our Propionic Acid trans-2-Hexen-1-Yl Ester is produced and tested to meet the stringent requirements of the flavor and fragrance industry. Quality is assured through rigorous analytical controls including gas chromatography (GC) and organoleptic evaluation. Certificates of Analysis (COA) detailing purity, identity, and organoleptic properties are provided with each batch to ensure consistency and compliance with relevant standards such as FEMA GRAS and IFRA guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C/59-77°F). This material is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Keep away from heat, sparks, and open flame. For long-term storage, consider maintaining under an inert gas blanket such as nitrogen to preserve organoleptic quality.
