Industrial Applications of 105140-25-8
| Industry | Application | Process |
|---|---|---|
| Electroplating | Complexing and buffering agent for cyanide-free copper electroplating | Used in alkaline cyanide-free copper plating electrolytes to maintain stable pH (pH 10–12), improving deposit uniformity and adhesion |
| Electroplating | Copper plating additive for through-hole metallization in printed circuit boards (PCBs) | Acts as the primary complexing agent, forming stable, soluble complexes with copper ions to enable uniform filling of high-aspect-ratio vias |
| Electroplating | Environmentally compatible ligand alternative in electronic plating | Replaces cyanide-containing or strongly chelating amines (e.g., EDTA), reducing wastewater treatment complexity and complying with RoHS and REACH requirements |
| Biochemistry | Component of protein crystallization buffers | Leverages its broad buffering range (pH 7.5–9.5) and low interference with metal ion chelation to stabilize crystal growth conditions |
| Pharmaceutical Intermediates | Investigation as a drug carrier or sustained-release excipient | In laboratory-scale development, exploring the potential of its sodium sulfonate and hydroxyl groups to jointly enhance water solubility and biocompatibility |
