Products Description of Potassium phosphate CAS#778-53-2
1-Ethyl-2-pyrrolidone (NEP) is a clear, colorless liquid engineered to function as an advanced aprotic solvent. Distinguished by its strong solvency, low volatility, and low dielectric constant, it performs reliably across diverse chemical processes. Beyond its primary solvency capabilities, it plays a strategic role in facilitating transdermal drug delivery and acting as a chemical intermediate in organic synthesis.
