In the pursuit of scientific advancement and product development, the availability of robust chemical building blocks is indispensable. 4-Pyrazolecarboxylic Acid, identified by CAS number 37718-11-9, emerges as a pivotal heterocyclic intermediate, critical for numerous synthesis pathways in the pharmaceutical, agrochemical, and broader fine chemical industries. Understanding its role and how to effectively procure it is a key objective for many industry professionals.

Understanding the Chemical Identity of 4-Pyrazolecarboxylic Acid

4-Pyrazolecarboxylic Acid is defined by its molecular formula C4H4N2O2 and a molecular weight of 112.09. Its structure features a pyrazole ring, a five-membered heterocycle containing two adjacent nitrogen atoms, coupled with a carboxylic acid group. This combination renders it a versatile reactant. Typically presented as an off-white powder, its high melting point (around 282°C with decomposition) indicates its stability, making it amenable to a variety of reaction conditions. The consistent quality and availability of this intermediate are crucial for reproducible results in complex chemical processes.

Key Sectors Benefiting from this Intermediate

The utility of 4-Pyrazolecarboxylic Acid is widespread, with significant impact in several key sectors:

  • Pharmaceutical Industry: The pyrazole motif is a common structural element in many biologically active compounds, including pharmaceuticals. As a key intermediate, 4-Pyrazolecarboxylic Acid is utilized by drug discovery scientists and manufacturers to synthesize novel APIs and drug candidates. If your company requires pharmaceutical intermediates, sourcing this compound is often a critical step.
  • Agrochemical Development: Similarly, pyrazole derivatives are prevalent in modern agrochemicals, offering effective solutions for pest and weed control. Researchers in this field use 4-Pyrazolecarboxylic Acid to develop innovative crop protection agents.
  • Fine Chemical and Research Applications: Beyond these major fields, it serves as a fundamental building block in various organic synthesis projects, enabling the creation of new functional materials and specialty chemicals. Its broad applicability makes it a staple in many research laboratories.

Strategic Sourcing for Procurement Managers

For procurement specialists, ensuring a steady and cost-effective supply of 4-Pyrazolecarboxylic Acid is a strategic imperative. Key considerations include:

  • Supplier Verification: It is essential to partner with reputable manufacturers and suppliers who can provide detailed product specifications, including purity (e.g., 95% or 98%) and a Certificate of Analysis (CoA).
  • Production Capacity: Evaluate the supplier's 'Supply Ability' and production capacity to ensure they can meet your current and future demand. Manufacturers located in China are often leaders in this regard.
  • Pricing and Value: Obtaining multiple quotes and comparing pricing from different manufacturers is crucial to secure the best value for your purchase.
  • Logistics and Terms: Understanding payment terms (L/C, T/T, etc.) and delivery options (FOB, CFR, etc.) facilitates a smooth transaction process.

The Advantage of Global Sourcing

When it comes to purchasing intermediates like CAS 37718-11-9, sourcing from established manufacturers in China can offer significant advantages in terms of both cost and scale. These suppliers are equipped to handle large orders and often maintain rigorous quality control standards. By focusing on a strategic approach to sourcing, R&D teams and production facilities can ensure they have uninterrupted access to high-quality materials, thereby accelerating product development and market entry.
