Cyanopyrazine, also known chemically as Pyrazinecarbonitrile (CAS 19847-12-2), is a heterocyclic organic compound that plays a significant role as an intermediate in various chemical and pharmaceutical syntheses. For procurement managers and R&D scientists, understanding its properties, potential synthesis routes, and reliable supply chains is essential for successful project execution.

Chemical Identity and Key Properties

Cyanopyrazine is characterized by the presence of a pyrazine ring substituted with a nitrile group. Its key properties include:

  • CAS Number: 19847-12-2
  • Synonyms: Pyrazinecarbonitrile, 2-Cyanopyrazine, Cyanopyrazine
  • Appearance: Typically a clear, colorless to yellow liquid.
  • Melting Point: 18-20°C
  • Boiling Point: 87°C at 6 mmHg
  • Density: 1.174 g/mL at 25°C

These physical attributes are crucial for handling, storage, and integration into chemical processes. Its liquid form simplifies dispensing and reaction setup.

Synthesis and Applications

Historically, Cyanopyrazine has been synthesized through methods like the vapor-phase catalytic ammoxidation of 2-methylpyrazine. Its primary application is as a vital intermediate in the pharmaceutical industry, serving as a precursor to Pyrazinamide, an essential drug for treating tuberculosis. Beyond this critical role, Cyanopyrazine is also utilized in the broader fine chemical industry and in material science for the development of advanced materials like nitrogen-doped carbon nanoparticles.

Securing a Reliable Supply Chain

For businesses looking to buy Cyanopyrazine, identifying reputable manufacturers is paramount. China hosts a significant number of chemical suppliers capable of producing this compound to high standards. When evaluating suppliers, it's important to consider factors such as:

  • Purity Levels: For pharmaceutical applications, high purity (e.g., >99%) is often required.
  • Production Capacity: Ensure the supplier can meet your volume requirements, from R&D quantities to large-scale industrial production.
  • Pricing and Quotes: Obtaining multiple quotes from reliable manufacturers will help ensure competitive pricing.
  • Quality Assurance: Look for suppliers who provide Certificates of Analysis (CoA) and adhere to international quality management systems.
