N-Methyl-2-pyrrolidone

Description:

N-Methyl-2-pyrrolidone (NMP) is a colorless to pale yellow liquid with a characteristic amine-like odor. It is a polar aprotic solvent, known for its ability to dissolve a wide range of organic and inorganic compounds, making it valuable in various industrial applications, including pharmaceuticals, coatings, and electronics. NMP has a high boiling point and low volatility, which contributes to its effectiveness as a solvent in high-temperature processes. Its chemical structure features a five-membered lactam ring, which contributes to its solvent properties and reactivity. NMP is miscible with water and many organic solvents, enhancing its versatility. However, it is important to note that NMP has raised health and environmental concerns due to its potential reproductive toxicity and skin irritation. As a result, its use is regulated in certain applications, and safety precautions are recommended when handling this substance. Overall, N-Methyl-2-pyrrolidone is a significant solvent in various fields, but its safety profile necessitates careful management.

N-Methyl-2-pyrrolidone

CAS: 872-50-4

N-Methyl-2-pyrrolidone is a solvent that is used in the production of polymers, paints, and other products. It has been shown to be a potent inducer of cardiac arrhythmias in rats. N-Methyl-2-pyrrolidone also has been shown to have a linear calibration curve for electrochemical impedance spectroscopy (EIS) data from 0.1 M to 5 M. This property makes it useful for determining reaction mechanisms and surface methodology. NMP has been shown to have constant pressure experimental solubility data, which can be used for thermodynamic data and high resistance values. NMP is not toxic to humans or animals at concentrations up to 2000 mg/kg body weight, but it does cause congestive heart failure in rats at doses of 500 mg/kg body weight or higher.
