N-Ethyl-p-toluenesulfonamide (N-PTSA) is a white crystal commonly used as a pharmaceutical intermediate. It is synthesized by reacting ethyl acetoacetate with p-toluenesulfonyl chloride under alkaline conditions. In the pharmaceutical industry, N-PTSA is utilized in the synthesis of various drugs. The presence of ethyl and p-toluenesulfonamide groups in its structure makes N-PTSA valuable for specific applications in drug synthesis. Additionally, N-PTSA is employed as a plasticiser to enhance polymers more reactivity[1].
