2,5-dimercaptoterephthalic acid Chemical Properties,Uses,Production
Uses
2,5-Dimercaptoterephthalic acid can be used as a ligand to coordinate with Zr(IV) to prepare thiol-functionalized Zr-DMBD MOFs. This material, loaded onto three-dimensional macroporous carbon, forms an electrochemical sensor integrating removal and detection, used for the sensitive determination of mercury ions in wastewater.
Synthesis
2,5-Dimercaptoterephthalic acid is mainly prepared by saponification reaction of S,S-dithiocarbamate with potassium hydroxide by heating.
