For procurement managers in the chemical and pharmaceutical industries, securing a consistent supply of high-quality raw materials is paramount. Tetradecanedioic acid (CAS 821-38-5) is one such crucial intermediate, valued for its long-chain dicarboxylic acid structure, which lends unique properties to a wide array of products. When looking to buy tetradecanedioic acid, understanding key sourcing factors will ensure your supply chain is robust and cost-effective.

Understanding Tetradecanedioic Acid (CAS 821-38-5)

Tetradecanedioic acid is a C14 alpha,omega-dicarboxylic acid. Its chemical structure, HOOC-(CH2)12-COOH, makes it an excellent building block for synthesizing polymers like polyamides and polyesters. These polymers find applications in high-performance plastics, fibers, and coatings due to their flexibility, strength, and thermal stability. Beyond polymers, it serves as a vital intermediate in organic synthesis and has biological relevance as an endogenous metabolite, making it useful in pharmaceutical research.

Key Factors for Sourcing Tetradecanedioic Acid

When evaluating suppliers, consider the following:

  • Purity and Specifications: Ensure the tetradecanedioic acid meets your required purity levels, typically 97% or higher. Critical specifications include melting point (124-127°C), appearance (white powder), and solubility (slightly in water, soluble in DMSO and methanol). A reputable manufacturer will provide detailed Certificates of Analysis (CoA).
  • Manufacturing Capabilities: Look for manufacturers with advanced production facilities and stringent quality control processes. Companies with experience in producing fine chemical intermediates, particularly dicarboxylic acids, are often preferred.
  • Supply Chain Reliability: For critical intermediates, supply chain stability is non-negotiable. Assess a supplier's production capacity, inventory management, and logistics capabilities to ensure timely delivery. Many companies prefer to source from established manufacturers in China due to competitive pricing and scale.
  • Price and Value: While cost is a significant factor, it should be balanced with quality and reliability. Obtaining quotes from multiple suppliers is essential to secure competitive pricing for bulk purchases. Negotiating long-term supply agreements can also offer price advantages.
  • Technical Support: A knowledgeable supplier can offer valuable technical support regarding product handling, storage, and application. This is particularly useful for custom synthesis or formulation challenges.

Finding Reliable Tetradecanedioic Acid Suppliers

When searching for a manufacturer or supplier, use precise search terms such as 'Tetradecanedioic Acid CAS 821-38-5 manufacturer,' 'buy tetradecanedioic acid China,' or 'tetradecanedioic acid price.' Online B2B platforms and chemical directories can be valuable resources for identifying potential partners. Always conduct thorough due diligence, including requesting samples, checking references, and verifying certifications.

Partnering with an experienced and reliable supplier of Tetradecanedioic Acid is key to the success of your downstream products. By focusing on quality, reliability, and competitive pricing, procurement managers can ensure a seamless supply of this essential chemical intermediate.
