Description

(Z)-13-Octadecenoic Acid Methyl Ester is a high-purity, unsaturated fatty acid methyl ester (FAME) of significant industrial interest. This compound serves as a crucial intermediate and reference standard in the synthesis of fine chemicals, pharmaceuticals, and advanced materials. It is primarily sought by manufacturers and R&D laboratories in the pharmaceutical, agrochemical, and specialty chemical sectors for applications requiring a defined cis-isomer of a C18:1 fatty acid derivative.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those targeting lipid metabolism.
• Agrochemical Synthesis: Serves as a key building block for manufacturing pesticides, herbicides, and plant growth regulators.
• Reference Standard: Employed as an analytical standard in gas chromatography (GC) and mass spectrometry (MS) for the identification and quantification of fatty acid profiles in oils and biological samples.
• Biochemical Research: Utilized in lipidomics studies and as a substrate for enzymatic studies involving lipases and desaturases.
• Specialty Polymer & Lubricant Additive: Acts as a monomer or modifier in the production of bio-based polymers and high-performance lubricants.
• Flavor & Fragrance Ingredient: Used in the synthesis of specific aroma compounds and flavoring agents.
