Description

(-)-Alloaromadendrene is a naturally occurring sesquiterpene hydrocarbon, a specific stereoisomer of alloaromadendrene. This compound is valued for its distinct woody, earthy, and slightly spicy aromatic profile, making it a sought-after ingredient in high-value fragrance compositions. It is primarily utilized by flavor and fragrance houses, aroma chemical manufacturers, and research institutions focused on natural product chemistry and olfactory science.

Application

• Fragrance Formulation: A key building block for creating complex, naturalistic woody, ambery, and spicy accords in perfumes, fine fragrances, and personal care products.
• Aroma Chemical Synthesis: Serves as a chiral starting material or intermediate for the synthesis of more complex fragrance molecules and flavorants.
• Flavor Enhancement: Used in trace amounts to add depth and natural woody nuances to specialty flavors.
• Standard Reference Material: Employed in analytical laboratories for GC-MS identification and quantification of sesquiterpenes in essential oils and plant extracts.
• Academic & Industrial Research: Used in studies concerning terpene biosynthesis, olfactory receptor interactions, and natural product isolation.
