Description

2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,9-Heptadecafluorononanal is a high-value perfluorinated aldehyde building block, prized for its ability to impart extreme hydrophobicity, oleophobicity, and chemical resistance to advanced materials. Its unique structure, featuring a terminal aldehyde group and a long perfluoroalkyl chain, makes it a critical intermediate for synthesizing specialized surfactants, polymers, and surface modifiers. This compound is essential for R&D and production in industries demanding high-performance fluorochemicals, such as electronics, specialty coatings, and advanced material science.

Application

• Fluorinated Surfactant & Polymer Synthesis: Serves as a key monomer for creating high-performance, low-surface-energy polymers and surfactants used in fire-fighting foams, coatings, and leveling agents.
• Water & Oil Repellent Finishes: Used to manufacture durable finishes for textiles, leather, and paper, providing exceptional stain and liquid resistance.
• Electronic & Semiconductor Materials: Employed in the synthesis of dielectric materials, photoresists, and anti-reflective coatings for microelectronics due to its thermal and chemical stability.
• Specialty Coatings & Adhesives: A precursor for fluorinated additives that enhance the performance of industrial coatings, paints, and adhesives, improving weatherability and reducing friction.
• Pharmaceutical & AgroChemical Intermediates: Acts as a building block for introducing perfluoroalkyl groups into bioactive molecules, potentially modifying their pharmacokinetic properties.
• Surface Modification Agent: Used to functionalize surfaces (e.g., glass, metals, polymers) to create highly hydrophobic and anti-fouling properties.

Quality Control

Our production of 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,9-Heptadecafluorononanal adheres to a strict quality management system. Every batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We support custom synthesis and can tailor purity grades to meet specific R&D or commercial application requirements.

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). Due to its sensitivity to strong bases and reactive fluorides, keep away from incompatible materials. For long-term storage under inert atmosphere, please contact our technical team for specific recommendations.
