N-Ethyl-p-toluenesulfonamide

N-Ethyl-p-toluenesulfonamide (CAS 80-39-7) is a sulfonamide-based chemical commercially known as Santicizer 3 and abbreviated as N-E-PTSA. It carries no assigned E-code and is also referenced as N-Tosylethylamine or Ethyl toluenesulfonamide in trade documentation. It falls under HS code 29350090 for customs classification within the EU.

In plastics processing, N-E-PTSA functions as a plasticizer by intercalating between polymer chains to reduce intermolecular forces, improving flexibility in polyamide and cellulosic systems. In textile and leather finishing, it acts as a solvent carrier, dissolving active agents and controlling their release onto substrates. Metalworking formulators incorporate it as a lubricant additive where its sulfonamide group provides boundary lubrication under pressure.

N-E-PTSA is supplied as an off-white crystalline solid and is subject to REACH registration requirements for EU import and use. No FCC or Ph.Eur. monograph applies to this industrial-grade material. Procurement teams should confirm SDS documentation and packaging specifications directly with the supplier.
