Perfluorododecanoic Acid (PFDoA), identified by CAS number 307-55-1, is a significant perfluorinated carboxylic acid (PFCA) that plays a role in several industrial applications. Understanding its inherent properties is crucial for researchers and product developers aiming to leverage its unique characteristics. As a highly fluorinated compound, PFDoA exhibits remarkable stability and distinct surface properties.

Chemical Composition and Physical Traits

PFDoA is characterized by its long, fully fluorinated carbon chain (C12) and a terminal carboxylic acid group. Its molecular formula is C12HF23O2, with a molecular weight of approximately 614.10 g/mol. Typically supplied with a purity of 97% or higher, it presents as a white powder or solid chunks. The compound's high density (1.769 g/cm³) and relatively high boiling point (245°C) are indicative of its robust chemical structure.

Key Industrial Applications

The unique hydrophobic and oleophobic nature imparted by the perfluorinated chain makes PFDoA valuable in various applications:

  • Surface Coatings: Historically used in stain and grease-proof coatings for food packaging, furniture, and carpets, it enhances resistance to oils, water, and stains.
  • Textile Treatments: Incorporated into finishes for textiles to provide water and stain repellency, improving the performance and durability of fabrics.
  • Industrial Fluids: Its thermal stability and chemical inertness can make it suitable for specialized industrial fluid formulations.
  • Chemical Intermediates: Serves as a building block or intermediate in the synthesis of more complex fluorinated chemicals and materials for niche applications.

Sourcing and Considerations for Manufacturers

For manufacturers and procurement specialists looking to buy Perfluorododecanoic Acid, sourcing from reliable manufacturers is essential. When you purchase PFDoA from a reputable supplier, you can expect consistent product quality, competitive pricing, and technical support. Understanding the specific grade and purity required for your application is vital. While PFDoA offers beneficial properties, its persistence in the environment is a factor that industry stakeholders must consider.

Engaging with a knowledgeable supplier who can provide detailed specifications, safety data sheets (SDS), and potential application guidance will streamline the procurement process. Exploring options from experienced manufacturers in regions like China often presents opportunities for cost-effective procurement of high-purity chemicals like PFDoA.
