Description

1-Methyl-1H-Pyrazole-3,5-Dicarboxylic Acid is a versatile heterocyclic dicarboxylic acid derivative that serves as a critical building block in advanced organic synthesis. Its value lies in its bifunctional structure, offering two carboxylic acid handles for derivatization and a protected pyrazole nitrogen, making it an essential precursor for pharmaceuticals and agrochemicals. This compound is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, inflammation, and metabolic diseases.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where the pyrazole core contributes to biological activity.
• Ligand and Catalyst Preparation: Serves as a precursor for chelating ligands in coordination chemistry and catalysis, useful in asymmetric synthesis and material science.
• Polymer and Material Science: Functional monomer for creating polyamides, polyimides, and other high-performance polymers with specific thermal or chemical resistance.
• Research & Development: A valuable scaffold in medicinal chemistry for structure-activity relationship (SAR) studies and library synthesis for high-throughput screening.
• Coordination Chemistry: Used to synthesize metal-organic frameworks (MOFs) and complexes for applications in gas storage, separation, and sensing.

Quality Control

Our 1-Methyl-1H-Pyrazole-3,5-Dicarboxylic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request, providing full traceability and compliance assurance for your regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. For long-term storage, consider using desiccants.
