Description

1-(2-Methoxyethyl)-3-Methyl-1H-Pyrazole-5-Carboxylic Acid is a versatile pyrazole carboxylic acid derivative that serves as a critical building block in advanced organic synthesis. Its value lies in its functionalized heterocyclic structure, which is essential for constructing complex molecules with targeted biological or material properties. This high-purity intermediate is primarily needed by pharmaceutical R&D teams, agrochemical manufacturers, and specialty chemical companies developing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for candidates targeting central nervous system (CNS) disorders and metabolic diseases.
• Agrochemical Synthesis: Building block for developing novel herbicides, fungicides, and insecticides, leveraging the pyrazole core for bioactivity.
• Ligand and Catalyst Development: Used in organometallic chemistry to create chelating ligands for catalytic systems and metal-organic frameworks (MOFs).
• Material Science Research: Intermediate for synthesizing specialty polymers, dyes, and photoactive compounds.
• Chemical Biology Probes: Serves as a scaffold for creating molecular probes and inhibitors used in biochemical and cellular research.
• Custom Synthesis and Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for custom synthesis projects under cGMP or research-grade conditions.

Quality Control

Our production of 1-(2-Methoxyethyl)-3-Methyl-1H-Pyrazole-5-Carboxylic Acid adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with each shipment, documenting all critical quality attributes. Our quality system is designed to support both research and development-scale projects and pre-clinical cGMP requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
