Description

3-(Aminosulfonyl)-4-Bromobenzoic Acid is a high-purity brominated benzoic acid derivative featuring both a sulfonamide and a carboxylic acid functional group. This unique bifunctional structure makes it a versatile and valuable chemical intermediate for advanced synthesis in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists for constructing complex molecules, particularly in the development of active pharmaceutical ingredients (APIs) and specialty crop protection agents.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel drug candidates, especially those targeting enzymes where the sulfonamide moiety can act as a pharmacophore.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides, leveraging the bromine atom for further functionalization.
• Organic Synthesis Reagent: Serves as a precursor for creating more complex sulfonamide-containing compounds or for introducing the carboxylic acid group into molecular frameworks.
• Material Science Research: Potential use in the development of specialty polymers, ligands for metal-organic frameworks (MOFs), or functionalized surfaces.
• Chemical Reference Standard: Employed in analytical laboratories for method development, calibration, and quality control testing of related substances.

Quality Control

Every batch of 3-(Aminosulfonyl)-4-Bromobenzoic Acid is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment to guarantee traceability and consistency for your critical synthesis work.

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 after opening to prevent degradation from atmospheric moisture.
