For procurement managers and R&D scientists in the chemical and pharmaceutical sectors, securing a consistent and high-quality supply of essential intermediates is critical for uninterrupted production and groundbreaking research. Diethyl D-Tartrate (CAS 13811-71-7) is one such compound, highly valued for its role as a chiral building block and its diverse applications. This buyer's guide focuses on what professionals need to know when they seek to purchase Diethyl D-Tartrate, emphasizing key factors like purity, application suitability, and the importance of reliable sourcing from a trusted manufacturer.

The primary consideration when buying Diethyl D-Tartrate is its purity and enantiomeric excess. For pharmaceutical synthesis and other high-stakes applications, an assay of ≥99% is typically required, along with a clear, colorless liquid appearance. The compound's function as a chiral auxiliary in asymmetric synthesis means that even minor impurities or racemic mixtures can significantly impact reaction outcomes, leading to lower yields or incorrect stereoisomers. Therefore, buyers should always request detailed specifications and Certificates of Analysis (CoA) from their suppliers. When looking for a supplier in China, prioritize those with certifications and a reputation for stringent quality control.

Understanding the intended application is also key to selecting the correct grade and quantity. Diethyl D-Tartrate is widely used in:

  • Pharmaceutical intermediates: For synthesizing APIs and complex drug molecules.
  • Agrochemicals: In the production of pesticides and herbicides with specific stereochemistry.
  • Food and Fragrance industries: As a flavoring and fragrance component.
  • Catalysis: As a precursor for chiral ligands and catalysts in asymmetric transformations.

Each of these areas may have slightly different purity requirements, though high enantiomeric purity is generally a constant. When considering where to buy Diethyl D-Tartrate, evaluate potential manufacturers based on their experience, production capacity, and ability to meet your volume needs. A competitive price is important, but it should not come at the expense of quality or reliability.

For businesses in need of this critical chemical, identifying a dependable Diethyl D-Tartrate manufacturer is paramount. Companies often look for suppliers who offer comprehensive technical support, flexible packaging options (e.g., 25kg drums), and efficient logistics. By conducting thorough due diligence and focusing on these key aspects, procurement professionals can ensure they secure a consistent supply of high-quality Diethyl D-Tartrate, thereby supporting their critical manufacturing and R&D endeavors effectively.
