Description

(Z)-2-Butenoic Acid Hexyl Ester is a high-purity, unsaturated fatty acid ester with a defined cis-configuration. This specific isomer is valued for its role as a versatile chemical intermediate and a potential flavor/fragrance component due to its characteristic fruity, waxy odor profile. It is primarily sought by manufacturers in the flavor & fragrance, pharmaceutical intermediates, and specialty polymer synthesis industries.

Application

• Flavor and Fragrance (F&F) Industry: Used as a building block or modifier in the synthesis of complex esters for creating fruity, green, or waxy olfactory notes in perfumes, cosmetics, and food flavorings.
• Pharmaceutical Intermediates: Serves as a key chiral synthon or precursor in the multi-step synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Specialty Polymer Production: Acts as a monomer or co-monomer in the production of specialized polymers, coatings, and resins, where its unsaturated bond allows for cross-linking or further functionalization.
• Organic Synthesis & Research: Employed in academic and industrial R&D laboratories as a reagent for studying stereoselective reactions, esterification processes, and as a model compound.
• Lubricant and Plasticizer Additives: Investigated for use as a bio-based or specialty additive to modify the properties of lubricants and polymeric materials.
