Description

(E)-4-((2-(4-Nitrophenyl)Hydrazono)Methyl)Benzene-1,3-Disulfonic Acid CAS NO 197583-89-4 is a specialized organic intermediate featuring a hydrazone linker and dual sulfonic acid groups, designed for high-value synthesis. This compound is critical for applications requiring precise molecular conjugation and strong water solubility due to its anionic character. It is primarily sought by research institutions and manufacturers in the pharmaceutical and advanced materials sectors for developing active pharmaceutical ingredients (APIs), dyes, and functional polymers.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel drug candidates, particularly those requiring azo-based linkers for targeted delivery.
• Dye and Pigment Synthesis: Used in the production of high-performance azo dyes and pigments, where the nitrophenyl and disulfonic acid groups contribute to color fastness and solubility.
• Chemical Sensor Development: Acts as a precursor for creating selective chemosensors, leveraging its hydrazone moiety for ion or molecule recognition.
• Polymer Functionalization: Employed to introduce sulfonic acid groups into polymers, enhancing properties like hydrophilicity and ion-exchange capacity for membrane or resin applications.
• Research & Development: Utilized in academic and industrial R&D for studying azo coupling reactions and developing new synthetic methodologies.
• Cross-linking Agent: Potential use in creating cross-linked hydrogels or networks for biomedical or separation technologies.

Quality Control

Our (E)-4-((2-(4-Nitrophenyl)Hydrazono)Methyl)Benzene-1,3-Disulfonic Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and high-purity standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

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 sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
