Description

(E)-5-Heptenoic Acid CAS NO 18776-90-4 is a high-purity, unsaturated medium-chain fatty acid derivative characterized by its terminal alkene group. This specific stereochemistry and functional group combination make it a valuable and versatile building block in advanced organic synthesis. It is primarily sought after by research institutions and industrial R&D departments for the development of novel compounds. Key industries utilizing this intermediate include pharmaceuticals, agrochemicals, and specialty materials.

Application

• Pharmaceutical Intermediate: Serves as a key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring specific carbon chain lengths and olefin geometry.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides, herbicides, and plant growth regulators where the heptenoic acid backbone is incorporated.
• Flavor & Fragrance Chemistry: Acts as a starting material for the synthesis of specific esters and lactones that contribute to complex flavor and fragrance profiles.
• Polymer & Material Science: Employed as a monomer or co-monomer in research for creating specialized polymers with tailored properties via the reactive double bond.
• Organic Synthesis Building Block: Utilized in cross-coupling reactions, hydrogenation, hydroformylation, and other catalytic processes to construct more complex molecular architectures.
• Biochemical Research: Used in metabolic studies and as an analog for naturally occurring fatty acids in biochemical pathway investigations.
