Description

.Delta.2-Trans Eicosenoic Acid CAS NO 2127095-72-9 is a high-purity, monounsaturated C20 fatty acid characterized by a specific trans-configuration at the δ2 position. This precise molecular structure makes it a valuable intermediate for advanced organic synthesis and pharmaceutical research, where stereochemical control is critical. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for applications requiring defined fatty acid derivatives.

Application

• Pharmaceutical Intermediate: Used in the synthesis of bioactive molecules, lipid-based drug conjugates, and prodrugs.
• Biochemical Research: Serves as a standard or building block in lipidomics, metabolic pathway studies, and membrane biophysics research.
• Agrochemical Synthesis: Acts as a precursor for specialized surfactants, adjuvants, or active ingredients requiring specific fatty acid chains.
• Specialty Polymer Additive: Incorporated to modify the properties of polymers, coatings, or lubricants where a long-chain trans-acid is beneficial.
• Reference Standard: Utilized as an analytical standard in chromatography (GC, HPLC) for the identification and quantification of fatty acid isomers.
