Description

cis-Ethyl Cinnamate is the cis-isomer of ethyl cinnamate, an ester derivative of cinnamic acid. This specific stereoisomer is valued for its distinct aromatic profile and utility as a chemical intermediate in fine synthesis. It serves as a key building block for research and development chemists and manufacturers in the flavor, fragrance, and pharmaceutical sectors. The compound's defined structure allows for precise control in applications where stereochemistry influences odor, taste, or biological activity.

Application

• Flavor and Fragrance (F&F) Ingredient: Used as a synthetic aromatic component to impart sweet, balsamic, and fruity notes in perfumes, cosmetics, and food flavorings.
• Pharmaceutical Intermediate: Serves as a chiral precursor or building block in the synthesis of more complex active pharmaceutical ingredients (APIs) and fine chemicals.
• Organic Synthesis Research: Employed in academic and industrial R&D for studying esterification reactions, isomerization processes, and as a model compound in stereochemistry.
• Specialty Chemical Manufacturing: Acts as an intermediate in the production of agrochemicals, liquid crystals, and other performance chemicals where specific isomer purity is critical.
