Description

(E)-2,3,4,4,5,5,5-Heptafluoro-2-Pentenoic Acid is a highly fluorinated, unsaturated carboxylic acid characterized by its strong acidity and unique perfluoroalkyl chain. This compound matters as a versatile and potent building block for introducing heptafluoropentene functionality into complex molecules, enabling the synthesis of advanced materials with tailored properties. It is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring fluorinated intermediates.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for introducing fluorine atoms to enhance metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in creating advanced herbicides, pesticides, and fungicides where the fluorinated moiety can improve efficacy and environmental profile.
• Fluorinated Polymer & Material Science: Acts as a monomer or modifier in the production of specialty polymers, surfactants, and coatings, imparting oil/water repellency, chemical resistance, and low surface energy.
• Liquid Crystal & Electronic Chemicals: Employed in the development of fluorinated liquid crystals and dielectric fluids for high-performance display and electronic applications.
• Organic Synthesis & Catalysis: Functions as a strong organic acid catalyst or a unique reagent in various fluorination and coupling reactions in advanced organic chemistry.

Quality Control

Our (E)-2,3,4,4,5,5,5-Heptafluoro-2-Pentenoic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and titration, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its nature as a strong acid/organic solvent, containers must be kept tightly sealed and constructed of compatible materials (e.g., fluoropolymer-lined). Recommended storage temperature: 2-8°C for long-term stability.
