Description

(Z,E)-Farnesal is a high-purity, unsaturated sesquiterpene aldehyde with a distinctive floral and woody aroma. This compound serves as a critical intermediate and active ingredient in the synthesis of complex fragrance molecules and bioactive compounds. It is essential for manufacturers in the flavors & fragrances, cosmetics, and fine chemical synthesis industries seeking reliable, high-quality raw materials for premium product formulations.

Application

• Fragrance & Flavor Ingredient: A key building block for synthesizing sophisticated perfume compounds like farnesol and nerolidol, imparting floral, green, and woody notes.
• Cosmetic & Personal Care: Used as a functional ingredient and fragrance component in high-end lotions, creams, and other personal care products.
• Fine Chemical Synthesis: Acts as a versatile chiral intermediate in the production of pharmaceuticals, vitamins (e.g., Vitamin E, K), and other specialty organic compounds.
• Pheromone & Agrochemical Research: Serves as a precursor in the development of insect pheromones and other biologically active agents for agricultural applications.
• Aroma Chemical Production: A fundamental material for creating a wide range of aroma chemicals used in consumer goods and industrial applications.

Quality Control

Our (Z,E)-Farnesal is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including GC and HPLC analysis, to ensure high purity and consistent isomer ratio. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support customer audits and can provide material for qualification under cGMP guidelines where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, and well-ventilated place at 2-8°C for long-term stability. This product is easily oxidized and light-sensitive; prolonged exposure to air, heat, or light should be avoided to prevent degradation.
