Description

Octadecanoyl Fluoride is a high-purity, long-chain fatty acid fluoride derivative, also known as stearoyl fluoride. This reactive intermediate is valued for its role as a versatile acylating agent in complex organic synthesis, enabling the efficient introduction of the stearoyl moiety. It is essential for research and production in advanced material science, pharmaceutical development, and specialty chemical manufacturing where precise molecular construction is required.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) and prodrugs, particularly in lipid-based drug formulations.
• Polymer & Material Science: Used in the synthesis of specialty polymers, surface-modifying agents, and fluorinated materials to alter surface properties.
• Organic Synthesis: Acts as a highly reactive acyl fluoride reagent for peptide coupling, esterification, and amidation reactions under mild conditions.
• Lubricant & Surfactant Additive Precursor: Serves as a starting material for manufacturing high-performance lubricant additives and specialized surfactants.
• Agrochemical Synthesis: Intermediate in the production of certain herbicides, pesticides, and plant growth regulators.
• Laboratory Research: A critical reagent in academic and industrial R&D for exploring new synthetic pathways and material properties.
