Description

7-Chloro-Indazol-4-Amine is a high-purity, synthetically versatile heterocyclic building block of significant interest in advanced organic synthesis. Its core value lies in its functionalized indazole scaffold, which serves as a privileged structure for developing novel pharmacologically active compounds. This intermediate is essential for research and development chemists working in pharmaceutical discovery and fine chemical manufacturing, particularly for creating targeted libraries and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A key synthon for the research and development of new drug candidates, particularly in oncology, neurology, and anti-inflammatory therapeutic areas.
• Agrochemical Research: Used in the synthesis of novel herbicides, fungicides, and insecticides, leveraging its heterocyclic core for bioactivity.
• Material Science Precursor: Serves as a building block for advanced organic materials, including ligands for catalysis and components for organic electronics.
• Chemical Biology Probe Development: Utilized to create tool compounds and molecular probes for studying biological pathways and target validation.
• Custom Synthesis & Contract Manufacturing: A critical starting material for fine chemical suppliers and CDMOs (Contract Development and Manufacturing Organizations) producing bespoke compounds for clients.

Quality Control

Our 7-Chloro-Indazol-4-Amine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality commitment aligns with cGMP principles for pharmaceutical intermediates, ensuring reliability for your most critical R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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.
