Description

Allyl perfluoropentanoate (CAS No. 84145-17-5) is a high-purity fluorinated ester with the molecular formula C₈H₅F₉O₂. Its IUPAC name, prop-2-enyl 2,2,3,3,4,4,5,5,5-nonafluoropentanoate, reflects its unique structure featuring a reactive allyl group and a perfluorinated pentanoate chain. This compound is characterized by its exceptional chemical stability, hydrophobicity, and oleophobicity, making it invaluable in advanced material synthesis and surface modification applications. Supplied as a clear, colorless to pale yellow liquid, it is rigorously tested for purity (typically ≥97% by GC) and stored under inert conditions to ensure optimal shelf life. Ideal for researchers in fluorochemistry, polymer science, and coatings, this reagent is packaged in amber glass bottles with secure closures to prevent moisture ingress and degradation.
