Description

(E)-2-Methylbutyl 3-phenyl-2-propenoate, also known by its systematic name 2-Propenoic Acid, 3-Phenyl-, 2-Methylbutyl Ester, (E)-, is a high-purity specialty ester valued for its unique aromatic properties and structural functionality. This compound serves as a critical intermediate and performance additive in advanced material synthesis, where its specific stereochemistry and ester group are essential. It is primarily sought by manufacturers in the fragrance, pharmaceutical, and specialty polymer industries for creating sophisticated olfactory profiles, active pharmaceutical ingredients (APIs), and functional monomers.

Application

• Fragrance and Flavor Industry: Used as a key intermediate or building block in the synthesis of complex aromatic esters and musk analogs, contributing to long-lasting and distinctive scent profiles in perfumes, cosmetics, and personal care products.
• Pharmaceutical Intermediates: Acts as a chiral synthon or protecting group in the multi-step synthesis of active pharmaceutical ingredients (APIs), particularly those requiring specific (E)-configured olefinic linkages.
• Specialty Polymer Production: Employed as a functional monomer or cross-linking agent in the manufacture of advanced polymers, including UV-curable resins, adhesives, and coatings, where the phenyl group enhances rigidity and refractive index.
• Organic Synthesis & Research: Serves as a versatile reagent in academic and industrial R&D laboratories for Michael additions, esterification studies, and the construction of more complex organic molecules.
• Liquid Crystal and Electronic Materials: Investigated for use in the development of organic semiconductors and liquid crystal displays (LCDs) due to its conjugated system and potential for charge transport.
