Description

3-Ethyl-4-Methyl-1H-Pyrazole Hydrochloride is a high-purity organic salt derivative of a substituted pyrazole, serving as a critical building block in advanced chemical synthesis. Its value lies in providing a functionalized heterocyclic core with enhanced solubility and reactivity for the development of novel compounds. This intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for creating active ingredients and specialty fine chemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders or acting as enzyme inhibitors.
• Agrochemical Synthesis: Building block for developing new generation pesticides, herbicides, and fungicides with improved efficacy and selectivity.
• Ligand and Catalyst Development: Used to create specialized pyrazole-based ligands for metal complexes in catalytic applications and material science.
• Chemical Research & Development: Fundamental scaffold for medicinal chemistry programs and structure-activity relationship (SAR) studies in academic and industrial R&D.
• Fine Chemical Production: Intermediate in the multi-step synthesis of complex organic molecules for electronics, dyes, and specialty polymers.

Quality Control

Our 3-Ethyl-4-Methyl-1H-Pyrazole Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specifications and test results to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
