DOI: 10.1039/d2ra07250e

Abstract: In this study, first, the electrochemical behavior of 2-amino-5-mercapto-1,3,4-thiadiazole (AMT) was fully investigated in the absence and presence of electrochemically generated p-benzoquinone (p-BQ, which is the oxidized form of hydroquinone), as an electrophile, via cyclic… read more here.
