Description

Bisphenol A Bissulfate Disodium Salt is a high-purity, water-soluble derivative of bisphenol A, widely recognized for its role as a key synthetic intermediate. This compound is valued for its ability to introduce sulfonate functionality, enhancing solubility and reactivity in advanced chemical synthesis. It is primarily sought by manufacturers in the pharmaceutical, polymer, and specialty chemical industries for the production of specialized monomers, surfactants, and functional materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs requiring sulfonate groups for improved bioavailability.
• Polymer Modification: Acts as a monomer or co-monomer for creating sulfonated polymers, ion-exchange resins, and specialty polycarbonates with enhanced properties.
• Surfactant & Detergent Synthesis: Serves as a precursor for anionic surfactants and emulsifiers used in industrial and institutional cleaning formulations.
• Crosslinking Agent: Employed in the production of thermosetting resins and coatings to improve chemical resistance and mechanical strength.
• Research & Development: A valuable building block in organic and medicinal chemistry research for constructing complex molecular architectures.
• Water Treatment Chemicals: Used in the formulation of scale inhibitors and dispersants for industrial water systems.

Quality Control

Our Bisphenol A Bissulfate Disodium Salt is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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 quality and handling.
