Description

(E,Z)-α-Farnesene is a naturally occurring sesquiterpene hydrocarbon, a key component in the characteristic aroma of apples and other fruits. This compound matters as a crucial semiochemical in plant defense and communication, and it serves as a valuable fragrance and flavor intermediate. Industries that need it include producers of agrochemicals, flavor & fragrance (F&F) compounds, and researchers in chemical ecology and green chemistry.

Application

• Agrochemical Formulations: As a key alarm pheromone and signaling molecule in integrated pest management (IPM) strategies.
• Flavor & Fragrance Industry: A vital intermediate for synthesizing complex aroma chemicals, imparting green, fruity, and woody notes.
• Chemical Ecology Research: Used in studies of plant-insect interactions, herbivore deterrence, and intra-plant signaling.
• Semiochemical Production: A precursor for manufacturing insect pheromones and other behavior-modifying compounds for sustainable agriculture.
• Standard & Reference Material: For analytical laboratories in quality control of food, essential oils, and plant extracts.
• Green Chemistry Synthesis: As a building block for the synthesis of more complex terpenoids and natural product analogs.

Quality Control

Our (E,Z)-α-Farnesene is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR, to ensure identity, purity, and isomer ratio conformity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and meet the stringent requirements of research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation and polymerization. Due to its highly volatile nature, keep containers tightly sealed in a cool, well-ventilated area away from heat and ignition sources.
