Description

5-Amino-2-Fluoro Benzene Sulfonic Acid is a versatile aromatic sulfonic acid derivative that serves as a critical building block in advanced organic synthesis. Its unique structure, featuring both an amino and a sulfonic acid group on a fluorinated benzene ring, makes it an essential intermediate for creating high-value, functionalized compounds. This product is primarily sought after by manufacturers in the pharmaceutical and specialty chemical industries for the development of active pharmaceutical ingredients (APIs), dyes, and agrochemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly for sulfonamide-based therapeutics and fluorinated APIs.
• Dye and Pigment Manufacturing: Used in the production of acid dyes and fluorescent brightening agents due to its sulfonic acid group, which improves water solubility and fiber affinity.
• Agrochemical Synthesis: Serves as a building block for creating advanced herbicides, fungicides, and plant growth regulators that benefit from fluorine's metabolic stability.
• Liquid Crystal & Electronic Materials: Employed in the synthesis of functional monomers and charge-control agents for electronic applications.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D in exploring new fluorinated aromatic compounds and heterocycles.
• Complexing Agent Precursor: Can be further functionalized to create ligands and chelating agents for metal ion sequestration.

Quality Control

Our 5-Amino-2-Fluoro Benzene Sulfonic Acid is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for use in sensitive applications like pharmaceutical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and strong acid properties, the container must be kept sealed to exclude moisture and stored separately from bases and reactive materials.
