Is NMP aprotic solvent?

N-Methyl-2-Pyrrolidone (NMP) is a high boiling, polar aprotic, low viscosity liquid. NMP has a good solvency for a wide range of organic and inorganic compounds and it is miscible with water at all temperatures and has a high chemical and thermal stability.

Is NMP acidic or basic?

NMP is stable under neutral conditions, but it is easy to open loop under acidic or alkaline conditions to form acid and other products, and both alkali and temperature have effects on the hydrolysis of NMP[9].

Is NMP a VOC?
