Description

5-Carboxyindazole Hydrochloride is a high-purity organic building block and pharmaceutical intermediate of significant commercial interest. Its core value lies in its functionalized indazole scaffold, which is a privileged structure in medicinal chemistry for designing novel bioactive molecules. This compound is primarily needed by research institutions and pharmaceutical companies engaged in the development of new therapeutic agents, particularly for oncology and CNS disorders.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of complex drug candidates, especially kinase inhibitors and receptor modulators.
• Organic Synthesis Building Block: Used to introduce the carboxyindazole moiety into larger molecular frameworks for structure-activity relationship (SAR) studies.
• Biochemical Research: Employed as a standard or reagent in enzymatic assays and biochemical pathway investigations.
• Agrochemical Research: Serves as a starting material for the development of novel crop protection agents and herbicides.
• Material Science: Potential monomer or functional additive in the development of specialty polymers and advanced materials.

Quality Control

Our 5-Carboxyindazole Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR), to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed batch-specific results are available upon request.

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.
