Description

cis-2-Hexenal is a highly reactive, naturally occurring aldehyde with a powerful, fresh, green, leafy aroma characteristic of cut grass. This compound is a key flavor and fragrance intermediate prized for its ability to impart natural, vegetative top notes. It is essential for manufacturers in the flavor and fragrance, food and beverage, and agrochemical industries seeking to create authentic green profiles or utilize its biological activity.

Application

• Flavor & Fragrance Formulation: A primary building block for creating fresh, green, and leafy notes in perfumes, colognes, air fresheners, and fabric conditioners.
• Food & Beverage Flavoring: Used to replicate the fresh, green taste of vegetables (like tomato, cucumber, bell pepper) and fruits in processed foods, beverages, and savory flavor systems.
• Agrochemical Intermediates: Serves as a key synthon or semiochemical in the production of certain pesticides, herbicides, and insect pheromones.
• Aroma Chemicals & Synergy: Acts as a powerful modifier and top-note enhancer in complex aroma chemical blends, adding natural freshness and lift.
• Research & Development: Utilized in organic synthesis and biochemical research as a standard or starting material for studying plant volatiles and green leaf volatiles (GLVs).
• Natural Product Extraction & Enhancement: Employed to standardize or fortify the green character in natural essential oil extracts and absolutes.

Quality Control

Our cis-2-Hexenal is produced and tested under strict quality management systems. Each batch is analyzed to ensure high purity, consistent olfactory profile, and chemical identity. We provide comprehensive Certificates of Analysis (COA) detailing specifications for assay, isomeric purity, and key impurities. Our quality commitment supports compliance with relevant standards for flavor and fragrance applications, including FEMA GRAS and IFRA guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, well-ventilated place at 2-8°C. Due to its highly volatile and easily oxidized nature, minimize headspace and avoid prolonged exposure to air, heat, or light to maintain stability and prevent polymerization or degradation.
