N-Ethyl-o/p-toluenesulfonamide (NEOPTSA) is a chemical compound with a distinct set of properties that dictate its utility and handling procedures. Understanding these characteristics is vital for R&D scientists, formulators, and safety officers who work with this substance, whether for plasticization or as a synthetic intermediate. When you decide to buy NEOPTSA, consulting detailed technical information is the first step.

Chemical Structure and Properties

NEOPTSA has the molecular formula C9H13NO2S and a molecular weight of approximately 199.27 g/mol. Its structure features an ethyl group attached to the nitrogen atom of an o/p-toluenesulfonamide moiety. This specific arrangement contributes to its efficacy as a plasticizer, offering a balance of compatibility and performance.

Key physical properties often cited by manufacturers and suppliers include:

  • Appearance: Typically a straw-yellow to colorless, clear liquid.
  • Purity: High purity grades, often exceeding 99%, are common for industrial applications.
  • Solubility: It exhibits good solubility in common organic solvents and moderate solubility in water, which influences its use in various formulations.
  • Boiling Point: While exact boiling points can vary with pressure, it's a relatively high-boiling point liquid, suggesting good thermal stability for many applications.

Safe Handling and Storage

Proper handling and storage are crucial to maintain the quality of NEOPTSA and ensure workplace safety. As a chemical compound, direct contact with skin and eyes should be avoided. Recommended personal protective equipment (PPE) typically includes chemical-resistant gloves, safety goggles, and protective clothing. Good ventilation in the work area is also advised, especially when handling large quantities or at elevated temperatures.

Storage should be in a cool, dry, and well-ventilated area, away from incompatible materials such as strong oxidizing agents. Containers should be kept tightly closed to prevent contamination or moisture absorption. For those looking to purchase NEOPTSA, ensuring that the supplier provides comprehensive safety data sheets (SDS) is a standard practice.
