1. Electroplating Industry
Acid Copper Plating Brighteners and Additive Intermediates
• Printed Circuit Board (PCB) Electroplating: Particularly suitable for this field, yielding high-quality plating.
• Hardware Decorative Copper Plating, Electrolytic Copper Foil: As a new generation of high-performance intermediates, it can replace or be used in conjunction with SP/SPS to make the plating brighter and smoother, and enhance ductility and corrosion resistance.

2. Materials Science
Surface Modifiers and Nanomaterial Preparation
• Formation of Self-Assembled Monolayers: Can form ordered molecular films on the surface of gold-plated substrates through chemical adsorption.
• Functionalized Gold Nanoparticles: Used as a capping agent to modify the surface of gold nanoparticles, applied in radiotherapy, drug delivery, and other fields.
• Preparation of Rhodium Nanoparticles: Used in the liquid-phase reduction method for preparing Rh nanoparticles.

3. Drug Delivery Systems
Functional Components of Nanocarriers
• Targeted Drug Delivery:
Using its functionalized gold nanoparticles as carriers, it can load drugs (such as dexamethasone) to achieve controlled drug release, showing potential in cancer treatment and other research.

4. Medical Treatment (Structural Analogues)
Cell Protectants and Surgical Aids
• Note: This application is mainly based on its structurally highly similar compound, sodium 2-mercaptoethanesulfonate. This drug has been clinically used to prevent chemotherapy-induced hemorrhagic cystitis and as a mucolytic agent in otological surgery.
