In the realm of chemical synthesis, the strategic sourcing of reliable intermediates is fundamental to innovation and production efficiency. 4-Pyrazolecarboxylic Acid, identified by its CAS number 37718-11-9, is a highly valuable heterocyclic building block that finds extensive application in the pharmaceutical and fine chemical industries. For R&D scientists and procurement managers, understanding its properties and sourcing options is paramount.

Key Properties and Applications of 4-Pyrazolecarboxylic Acid

4-Pyrazolecarboxylic Acid, with the molecular formula C4H4N2O2 and a molecular weight of 112.09, is characterized by its pyrazole ring and a carboxylic acid functional group. It typically appears as an off-white powder and possesses a high melting point (around 282°C, with decomposition), indicating good thermal stability. This makes it a versatile intermediate for various chemical transformations.

Its primary applications include:

  • Pharmaceutical Industry: It serves as a crucial intermediate in the synthesis of Active Pharmaceutical Ingredients (APIs) and novel drug candidates. Researchers often buy this compound to explore new therapeutic pathways due to the prevalence of pyrazole structures in medicinal chemistry.
  • Fine Chemical Synthesis: As a fundamental building block, it enables the creation of a wide range of specialty chemicals, contributing to advancements in material science and other chemical sectors.
  • Agrochemical Development: The pyrazole scaffold is also found in many effective agrochemicals, making this acid a valuable component for developing new crop protection solutions.

Navigating the Global Supply Chain: Finding Reliable Suppliers

For procurement professionals, identifying trustworthy manufacturers and suppliers is a critical step. When seeking to purchase 4-Pyrazolecarboxylic Acid, several factors are important:

  • Quality and Purity: Always ensure the supplier provides a Certificate of Analysis (CoA) detailing purity levels (commonly 95% or 98%) and other relevant specifications.
  • Manufacturer Capacity: Look for suppliers with significant 'Supply Ability' and a consistent production capability to meet ongoing demand. Manufacturers in China are often well-positioned to offer large quantities.
  • Competitive Pricing: Direct sourcing from manufacturers can lead to more favorable pricing. Obtaining multiple quotes is a standard practice to ensure cost-effectiveness.
  • Logistics and Payment: Understanding Incoterms, shipping options (Ocean, Land, Air), and accepted payment types (L/C, T/T, Paypal) is vital for a smooth transaction.

Why Choose China Manufacturers for 4-Pyrazolecarboxylic Acid?

Chinese chemical manufacturers have become a dominant force in the global supply of fine chemical intermediates. They often offer a combination of competitive pricing, large-scale production capabilities, and adherence to international quality standards. When you need to buy 4-Pyrazolecarboxylic Acid, sourcing from a reputable Chinese supplier can ensure timely delivery and cost efficiency for your research and production needs.

To effectively integrate 4-Pyrazolecarboxylic Acid into your projects, it's advisable to engage with suppliers who can provide comprehensive technical data and responsive customer support. This ensures that your procurement process is streamlined, allowing your team to focus on innovation and product development.
