Description

2-Hydrazino-5-Sulphobenzoic Acid is a specialized aromatic sulfonic acid derivative featuring a reactive hydrazine functional group. This unique bifunctional structure makes it a valuable chemical intermediate for synthesizing complex molecules in advanced manufacturing. It is primarily sought by pharmaceutical and fine chemical industries for the development of active ingredients and high-performance dyes.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a sulfonated aromatic core.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other colorants, where the hydrazino group is essential for chromophore formation.
• Chemical Research & Development: Used in organic synthesis for creating novel heterocyclic compounds and functional materials.
• Chelating Agent Synthesis: Acts as a starting material for producing ligands and chelating agents used in metal ion sequestration.
• Polymer Modification: Employed to introduce sulfonic acid and hydrazine functionalities into polymer chains to alter solubility or reactivity.
• Analytical Reagent: Utilized in the preparation of reagents for spectrophotometric analysis and detection of specific analytes.

Quality Control

Our 2-Hydrazino-5-Sulphobenzoic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of our industrial and research clients. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles 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 place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
