Description

5-Diazonio-2-[(Z)-2-(4-Diazonio-2-Sulfonato-Phenyl)Ethenyl]Benzenesulfonate is a specialized diazonium salt derivative, a high-value intermediate prized for its dual reactive sites and water-solubility imparted by the sulfonate groups. This compound matters for enabling precise, controlled chemical synthesis, particularly in the creation of advanced dyes, pigments, and functional polymers where stable diazonium coupling is required. It is primarily needed by R&D chemists and production specialists in the fine chemical, specialty dye, and advanced material manufacturing sectors.

Application

• Azo Dye & Pigment Synthesis: Serves as a critical coupling agent for producing high-performance, water-soluble azo dyes with enhanced color fastness and brightness.
• Functional Polymer Modification: Used to introduce diazonium functional groups onto polymer backbones for creating photosensitive or conductive materials.
• Surface Functionalization: Enables covalent bonding of organic layers to metal or semiconductor surfaces in sensor and electronic device fabrication.
• Bioconjugation & Probe Development: Acts as a linker for attaching reporter molecules or tags in diagnostic assay and bio-imaging research.
• Photoresist & Imaging Chemistry: A component in formulations for photolithography and other light-sensitive imaging processes.
• Cross-linking Agent: Utilized in the synthesis of cross-linked hydrogels or resins with specific ionic properties.

Quality Control

Every batch of our 5-Diazonio-2-[(Z)-2-(4-Diazonio-2-Sulfonato-Phenyl)Ethenyl]Benzenesulfonate undergoes rigorous analytical testing to ensure identity, purity, and consistency. We adhere to stringent in-house specifications developed for high-purity intermediates. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and other critical parameters is provided with each shipment 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under dry, inert conditions to prevent decomposition. Keep away from heat, sparks, and incompatible materials.
