It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide.
Metadoxine is an ion pair salt of pyridoxine and pyrrolidone carboxylate (PCA). [1] Pyridoxine (vitamin B 6 ) is a precursor of coenzymes including pyridoxal 5’-phosphate (PLP), which accelerates the metabolic degradation of ethanol and prevents adenosine triphosphate (ATP) inactivation by acetaldehyde .
2-Pyrrolidone, also known as 2-pyrrolidinone or butyrolactam, is an organic compound consisting of a 5-membered lactam, making it the simplest γ-lactam. It is a colorless liquid that is miscible with water and most common organic solvents.
The product used mainly for coatings is sold in a powdered form and is roughly 50% imidized. One of the major uses is as a magnet wire enamel. The magnet wire enamel is made by dissolving the PAI powder in a strong, aprotic solvent such as N-methyl pyrrolidone.
