Description

2-Butenoic Acid, 2-Methyl-, Ethyl Ester, (2Z)- is a high-purity, unsaturated ester with a defined stereochemistry, valued for its role as a versatile chemical intermediate and flavor/fragrance component. Its specific (Z)-configuration and ester functionality make it a critical building block in the synthesis of fine chemicals, agrochemicals, and specialty polymers. This product is essential for R&D laboratories, flavor & fragrance houses, and manufacturers in the agrochemical and pharmaceutical sectors seeking reliable, high-quality intermediates.

Application

• Flavor and Fragrance (F&F) Industry: Used as a key intermediate or aroma chemical for creating fruity, green, or waxy notes in perfumes, cosmetics, and food flavorings.
• Agrochemical Synthesis: Serves as a crucial precursor in the manufacture of certain pesticides, herbicides, and plant growth regulators.
• Pharmaceutical Intermediates: Acts as a building block in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Polymer Science: Utilized in the production of specialty polymers, coatings, and resins, where its unsaturated bond can participate in polymerization reactions.
• Organic Synthesis & R&D: A valuable reagent for academic and industrial research in synthetic organic chemistry, particularly in reactions involving α,β-unsaturated esters.
