Applications
8a-Isopropyl-3-methyl-1,2,4,5,8,8a-hexahydroazulene-6-carbaldehyde is an azulene-derived aldehyde that serves as a fragrance-related component and a building block for aroma chemistry. In practice, it is often used as a fragrance ingredient and intermediate in fragrance formulation; it may function as an odorant or fragrance fixative in perfumes, cosmetics and personal-care products; it can be evaluated for use in household products such as air fresheners and cleaners; it can act as an intermediate for the synthesis of more complex azulene-based fragrance compounds in industrial manufacturing; it may serve as a building block for specialty polymers and materials; and it could be explored as a component in coatings or inks where aroma or functional functionality is desired, subject to regulatory and formulation constraints.
