Contribution a l'Etude Electocimique de Derives de l'Acide Mercapto-2 Pyridinecarboxylique-5. I

Abstract

5-methoxycarbonoyl-1-methyl-2-thio-1,2-dihydropyridine and 1-metyl -2-thio-1,2-dihydropyridine-5-carboxylic acid heve been studied by recent electrochemical methods. The analysis of classical, alternative (A.C.) and pulse polarograms led to precise the nature of the observed currents. The pH variatiors and the supporting electrolyte modifications have an important influence on these currents.

Key Words:

• 2-mercapto-pyridine-5-carboxylic acid derivatives
• direct current
• alternative
• differential pulse polarography
