Description

5-Sulfoanthranilic Acid is an important sulfonated aromatic amino acid derivative, serving as a versatile intermediate in fine chemical synthesis. Its value lies in its bifunctional structure, containing both an amino and a sulfonic acid group, which enables its use in the production of dyes, pigments, and specialized pharmaceuticals. This compound is essential for manufacturers and R&D laboratories in the chemical, pharmaceutical, and agrochemical sectors seeking high-purity building blocks for complex molecular architectures.

Application

• Dye and Pigment Intermediate: A key precursor in the synthesis of acid dyes, reactive dyes, and organic pigments, contributing to color fastness and solubility.
• Pharmaceutical Synthesis: Used as a building block for active pharmaceutical ingredients (APIs), particularly in compounds requiring sulfonated aniline motifs.
• Agrochemical Manufacturing: Employed in the production of certain herbicides and plant growth regulators.
• Chemical Research & Development: A valuable reagent for synthesizing novel sulfonated compounds and conducting structure-activity relationship (SAR) studies.
• Liquid Crystal & Electronic Materials: Can be utilized in the synthesis of specialized monomers for advanced materials.
• Corrosion Inhibitor Formulation: Acts as a component in formulations designed to protect metal surfaces.

Quality Control

Our 5-Sulfoanthranilic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for industrial and research applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance and regulatory compliance needs.

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, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product stability and handling.
