  • Applications

    6-Azulenol, 1,2,3,3a,4,5,6,8a-octahydro-4,8-dimethyl-2-(1-methylethylidene)-, 6-propanoate (10486-26-7) is used primarily as a specialty chemical intermediate in fragrance chemistry, where the azulene scaffold supports distinctive notes and serves as a versatile handle for further derivatization. It may function as a fragrance ingredient or fixative in cosmetics and personal care products to help stabilize and extend aroma. In household products such as cleaners and air fresheners, it can contribute unique odor signatures. In industrial manufacturing, it is evaluated as an intermediate for synthesis of aroma-related derivatives and as a building block for specialty polymers/plastics with modified properties. In coatings and inks, it may be explored as a fragrance-release additive or functional modifier to impart scent characteristics or improve formulation stability.
