Description

3-Methyl-4-Oxo-4,7-Dihydro-1H-Pyrazolo[3,4-B]Pyridine-5-Carboxylic Acid Ethyl Ester is a high-value heterocyclic building block and pharmaceutical intermediate. Its fused pyrazolopyridine core structure makes it a critical precursor in the synthesis of novel active pharmaceutical ingredients (APIs) and fine chemicals. This compound is primarily sought by research institutions and manufacturers in the pharmaceutical, agrochemical, and advanced material sectors for developing new therapeutic agents and functional molecules.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, inflammation, and oncology.
• Agrochemical Research: Used in the development of new pesticides and herbicides, leveraging its heterocyclic scaffold for bioactivity.
• Organic Synthesis Reagent: Serves as a versatile precursor for constructing complex nitrogen-containing heterocycles in medicinal chemistry.
• Material Science Research: Potential precursor for the development of organic electronic materials or metal-organic frameworks (MOFs) due to its conjugated system and coordination sites.
• Contract Research & Development (CRO/CMO): Supplied to research organizations for custom synthesis and process development projects.

Quality Control

Our 3-Methyl-4-Oxo-4,7-Dihydro-1H-Pyrazolo[3,4-B]Pyridine-5-Carboxylic Acid Ethyl Ester is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment. We support cGMP compliance for pharmaceutical applications and can tailor purity grades to meet specific project requirements.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent degradation. Keep away from heat and incompatible materials.
