Description

4-Amino-2-Furancarboxylic Acid is a functionalized furan derivative that serves as a versatile building block in advanced organic synthesis. Its unique structure, featuring both an amino and a carboxylic acid group on the furan ring, makes it a critical intermediate for constructing complex heterocyclic compounds. This high-purity chemical is essential for research and development in the pharmaceutical and agrochemical industries, where it is used to develop novel active ingredients.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of novel drug candidates, particularly in antimicrobial and anti-inflammatory research.
• Agrochemical Synthesis: Used in the development of new herbicides, fungicides, and plant growth regulators.
• Organic Light-Emitting Diodes (OLEDs): Acts as a precursor for electron-transport materials or emissive layer components in electronic displays.
• Coordination Chemistry & Ligand Design: The amino and carboxylate groups can chelate metal ions, useful in creating catalysts or metal-organic frameworks (MOFs).
• Dye & Pigment Manufacturing: Intermediate for producing specialized heterocyclic dyes with specific colorfastness and light-absorption properties.
• Academic & Industrial R&D: Serves as a standard reagent for methodological studies in heterocyclic and medicinal chemistry.

Quality Control

Our 4-Amino-2-Furancarboxylic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and purity.
