Description

2-Nitro-3-Aminobenzoic Acid is a versatile aromatic compound featuring both nitro and amino functional groups on a benzoic acid backbone. This unique bifunctional structure makes it a valuable key intermediate in the synthesis of more complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is primarily sought after by R&D chemists and process development teams for constructing heterocyclic compounds, active pharmaceutical ingredients (APIs), and specialized dyes.

Application

• Pharmaceutical Intermediate: A crucial building block for the synthesis of various active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing quinoline or other fused heterocyclic systems.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where its aromatic nitro and amino groups serve as handles for further chemical modification.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other complex colorants, contributing to the chromophore structure.
• Research & Development: Employed in academic and industrial laboratories for method development and the creation of novel chemical entities for material science and medicinal chemistry.
• Coordination Chemistry: Can act as a ligand or precursor for ligands in metal-organic frameworks (MOFs) and catalysts due to its carboxylic acid and amino functionalities.

Quality Control

Our 2-Nitro-3-Aminobenzoic Acid is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and consistent high-quality standards. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which may affect product stability and handling properties.
