Applications of 129-16-8
| Industry | Application | Process |
|---|---|---|
| Analytical Chemistry | Fluorescent indicator for qualitative and quantitative detection of mercury ions (Hg²⁺) | Forms a fluorescent-enhancing or quenching complex with Hg²⁺ in weakly acidic to neutral buffered solution; quantified via fluorometric spectrophotometry |
| Biological Staining | Selective labeling of thiol (–SH)-containing proteins or enzyme active sites in histology | After fixation, cryosections or paraffin sections are incubated at room temperature in Tris buffer (pH 7.0–7.4); bound probe is visualized by fluorescence microscopy |
| Environmental Monitoring | Rapid on-site screening reagent for trace mercury contamination in water and soil samples | Following solid-phase extraction enrichment, reacts with sample extract; semi-quantitative colorimetric or portable fluorometric detection based on fluorescence intensity change |
