Understanding 1H-Pyrazole-4-carbonitrile's Chemical Identity

1H-Pyrazole-4-carbonitrile, often referred to by its CAS number 31108-57-3, is characterized by a white powder appearance and a high purity level (typically 97% minimum). The pyrazole ring, a five-membered heterocycle containing two adjacent nitrogen atoms, is renowned in medicinal chemistry for its inherent stability and its ability to interact with biological targets through hydrogen bonding and π-stacking. The addition of a nitrile group at the 4-position further enhances its synthetic utility, providing a reactive handle for subsequent chemical transformations and influencing the electronic properties of the molecule.

Key Synthetic Methodologies for Researchers

The synthesis of 1H-Pyrazole-4-carbonitrile derivatives is an area of active research, with a significant focus on green chemistry principles. Modern approaches aim for efficiency, high yields, and reduced environmental impact. Many synthetic routes leverage one-pot, three-component reactions, which are highly atom-economical. For example, the reaction between an aldehyde, malononitrile, and a hydrazine derivative is a common pathway. Green methodologies often employ:

  • Deep Eutectic Solvents (DESs): Systems like potassium carbonate/glycerol or choline chloride/urea offer environmentally friendly reaction media that can also act as catalysts.
  • Microwave-Assisted Synthesis: This technique significantly reduces reaction times and improves yields, offering a faster route to desired compounds.
  • Eco-Friendly Catalysts: The use of inexpensive and reusable catalysts such as sodium chloride or bio-derived catalysts (e.g., from neem leaves) is increasingly favored.

For procurement managers and R&D scientists, understanding these synthesis pathways is crucial when evaluating suppliers and ensuring the quality of the intermediate. Sourcing from a reliable manufacturer in China can provide access to these advanced synthetic capabilities.
