Uses

 2-Mercapto-N-(2-naphthyl)acetamide (CAS NO.93-42-5) is used for preconcentration of microgram levels of antimony(III) from aqueous solution loaded on glass beads with the aid of collodion. It is also used for rapid preconcentration of μg l−1 levels of palladium(II) from aqueous solution, followed by atomic absorption spectrometric measurement on silica gel. 2-Mercapto-N-(2-naphthyl)acetamide markedly inhibits biliary excretion of methyl mercury. Simultaneously, the sulfhydryl and sulphide content of bile decreases.
