说明

一般說明

1-Methylpyrrolidine is a heterocyclic organic compound that serves as a base and catalyst in organic reactions, such as aldol condensations, acylations, and cyclization reactions. Additionally, it is used as a solvent for certain polymerization processes due to its ability to dissolve both polar and non-polar substances. It exhibits strong nucleophilic properties because of the lone pair of electrons on its nitrogen atom, making it highly reactive towards electrophiles. This property enables its use in alkylation, acylation, and substitution reactions, facilitating the synthesis of diverse nitrogen-containing compounds.
