1-Methylpyrrolidine, CAS: 120-94-5

Key Applications:

• Organic Synthesis Intermediate

Used as a versatile building block for preparing pharmaceuticals, agrochemicals, specialty monomers, and heterocyclic derivatives. Its secondary amine functionality enables N‑alkylation, acylation, and reductive amination workflows.

• Catalysis and Reaction Promotion

Functions as a mild, non‑nucleophilic base in a variety of transformations, including elimination reactions, Michael additions, and condensation chemistry. Its cyclic structure provides predictable basicity and low steric hindrance.

• Polymer and Coatings Chemistry

Employed in the synthesis of functional polymers, crosslinkers, and curing agents. Its reactivity toward electrophiles supports tailored polymer architectures and surface‑modification strategies.

• Solvent and Process Aid

Utilized as a polar, aprotic co‑solvent or solubilizing agent in multistep synthesis, extraction, and purification processes. Its miscibility with common organic solvents makes it suitable for process intensification.

• Precursor to Ionic Liquids and Quaternary Salts

Serves as a key starting material for preparing N‑alkylpyrrolidinium salts, including halides, triflates, and bis(trifluoromethylsulfonyl)imide derivatives. These downstream materials are used in electrochemistry, battery electrolytes, catalysis, and separation science.

• Deblocking Reagent in Polymer and Protective‑Group Chemistry

Applied as a selective deblocking reagent for removing acid‑labile or thermally labile protecting groups, particularly in polyurethane, epoxy, and specialty coatings systems. Its basicity and cyclic structure enable efficient cleavage without excessive side reactions, supporting controlled curing and post‑functionalization.

• Analytical and Mechanistic Studies

Used as a model secondary amine in kinetic, mechanistic, and structure–reactivity investigations, especially in studies of amine basicity, nucleophilicity, and solvent effects.
