Pharmaceutical and Medical
1. Drug Formulation: NMP is used as a penetration enhancer in transdermal drug delivery systems (patches), helping active ingredients pass through the skin.
2. Synthesis Medium: It serves as a reaction medium (solvent) for the synthesis of various active pharmaceutical ingredients (APIs) due to its ability to dissolve both organic and inorganic compounds.
3. Medical Devices: Used in the processing and casting of medical-grade plastics and tubing.
Agrochemicals
Carrier Solvent: NMP is used as a carrier or co-solvent in pesticide, herbicide, and fungicide formulations. It helps the active ingredients dissolve properly and can aid in the penetration of the chemicals into plant leaves or insect cuticles.
Petrochemical Industry
1. Aromatics Extraction: NMP is a highly selective solvent used in the refining of crude oil. It helps separate valuable aromatic hydrocarbons (like benzene, toluene, and xylene) from non-aromatic compounds.
2. Acetylene and Butadiene Recovery: It is used to purify gas streams by selectively absorbing and recovering these specific hydrocarbons.
3. Lube Oil Treatment: It is employed in the solvent refining of lubricating oils to improve their viscosity index and oxidation stability.
