Description

4,5,5,5-Tetrafluoro-4-(trifluoromethyl)-2-pentenoic acid is a highly fluorinated unsaturated carboxylic acid, serving as a critical building block for advanced materials and pharmaceuticals. Its unique perfluorinated alkyl chain and reactive alkene moiety make it an invaluable intermediate for introducing lipophilicity and metabolic stability into target molecules. This compound is primarily sought by R&D and production teams in the agrochemical, pharmaceutical, and specialty polymer industries for synthesizing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key synthon for the development of novel active pharmaceutical ingredients (APIs), particularly those requiring enhanced bioavailability and metabolic resistance.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where the fluorine atoms contribute to biological activity and environmental persistence.
• Fluorinated Polymer Production: Serves as a monomer or modifier in the synthesis of specialty polymers, imparting oil, water, and stain resistance.
• Liquid Crystal & Electronic Materials: A precursor for fluorinated components in liquid crystal displays (LCDs) and dielectric materials.
• Surface Active Agents: Used to create fluorinated surfactants and coatings with exceptional surface tension-lowering properties.
• Organic Synthesis Building Block: Employed in cross-coupling reactions, Michael additions, and other transformations to construct complex fluorinated architectures.

Quality Control

Our production of 4,5,5,5-Tetrafluoro-4-(trifluoromethyl)-2-pentenoic acid adheres to stringent in-process controls and final batch release testing. Every lot is analyzed to ensure identity, purity, and consistency, with specifications tailored to meet the demanding requirements of pharmaceutical and advanced material applications. A comprehensive Certificate of Analysis (COA) detailing purity (typically by GC or HPLC), identity (by FT-IR and/or NMR), and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and a strong acid/organic solvent; containers must be kept tightly sealed to exclude moisture and stored separately from bases and reactive materials.
