Description

(2E)-2-Ethyl-4-(2,2,3-Trimethylcyclopent-3-En-1-Yl)But-2-En-1-Ol is a high-value fragrance intermediate and chemical building block prized for its unique woody, amber-like olfactory characteristics. This compound matters for formulators seeking to create sophisticated, long-lasting scent profiles in premium consumer products. Key industries that need it include the fragrance and flavor (F&F) industry for perfumes, cosmetics, and personal care items, as well as specialty chemical synthesis.

Application

• Fragrance Formulation: Serves as a key intermediate and modifier in the creation of woody, amber, and sandalwood-type perfume accords for fine fragrances, eau de toilettes, and aftershaves.
• Cosmetics & Personal Care: Used in scented lotions, soaps, shampoos, and deodorants to impart a stable and appealing base note.
• Household & Air Care Products: Incorporated into premium detergents, fabric softeners, and air fresheners for a sophisticated and persistent scent.
• Flavor Enhancement: Potential use in trace amounts to add complexity to certain flavor profiles, subject to regulatory approval and purity grade.
• Chemical Synthesis: Acts as a versatile chiral building block in organic synthesis for pharmaceuticals and other fine chemicals due to its specific stereochemistry and functional groups.
