Description

3-Ethanesulfonamidobenzoic Acid is a specialized organic intermediate featuring a benzoic acid core functionalized with an ethanesulfonamide group. This unique structure makes it a valuable building block for the synthesis of more complex molecules, particularly in pharmaceutical research and development. It is primarily sought after by R&D chemists and process development scientists in the fine chemical and pharmaceutical industries for creating novel active pharmaceutical ingredients (APIs) and other high-value compounds.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting specific enzyme pathways.
• Organic Synthesis Building Block: Used in research-scale and pilot-scale chemical reactions to introduce the sulfonamidobenzoate moiety into target molecules.
• Agrochemical Research: Serves as a starting material for developing new herbicides or fungicides with potential sulfonamide activity.
• Material Science: Potential monomer or additive in the development of specialized polymers with unique thermal or chemical properties.
• Bioconjugation Chemistry: The carboxylic acid group allows for coupling reactions, useful in creating probes or labeled compounds for biochemical studies.

Quality Control

Our 3-Ethanesulfonamidobenzoic Acid is produced under a strict quality management system. 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 development applications. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 after each use to prevent degradation from atmospheric moisture.
