Description

2-Amino-3-Chloropyrazine is a versatile heterocyclic building block with a fused aromatic structure containing both chlorine and amino functional groups. This unique combination of a halogen and an amine on the pyrazine ring makes it a critical intermediate for synthesizing complex molecules in advanced research and development. It is essential for B2B clients in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the development of novel drug candidates, particularly in kinase inhibitors and other targeted therapies.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides, leveraging its halogenated heterocyclic core.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands in coordination chemistry and catalysis.
• Material Science Research: Employed in the synthesis of organic electronic materials, such as components for OLEDs or conductive polymers.
• Chemical Biology Probes: Useful for constructing molecular probes and tags due to its reactive sites for further functionalization.
• Custom Synthesis and Contract Manufacturing: A fundamental building block for custom synthesis projects and scale-up processes in fine chemical production.

Quality Control

Our 2-Amino-3-Chloropyrazine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
