N-Ethylpyrrolidinone(CAS: 2687-91-4)

N-Ethylpyrrolidinone is a cyclic amide with the chemical formula C6H11NO. It is a colorless, clear liquid with a slightly sweet odor, known for its solubility in both water and organic solvents. This compound is widely used as a solvent and intermediate in chemical synthesis due to its stability and polarity. Its CAS number is 2687-91-4, and it is also referred to as 1-Pyrrolidinyl-2-propanone in some contexts.

N-Ethylpyrrolidinone (CAS: 2687-91-4) is primarily used in pharmaceuticals as a solvent for drug formulations and a key intermediate in synthesizing active pharmaceutical ingredients. It also serves as a solvent in the production of coatings, adhesives, and specialty chemicals. Additionally, it is employed in the food industry as a processing aid and in research for polymer synthesis and chemical derivatization.

N-Ethylpyrrolidinone (CAS: 2687-91-4) is generally considered safe when handled properly, with low toxicity in short-term exposure. However, it may cause mild skin or eye irritation. Safety guidelines recommend using appropriate protective equipment, such as gloves and goggles, and ensuring adequate ventilation. It is classified as a safe chemical in food applications under regulatory standards but should be treated with care in industrial settings.

N-Ethylpyrrolidinone (CAS: 2687-91-4) should be stored in a cool, dry place, preferably at 25°C or below, to maintain stability. It is hygroscopic, so storage in a sealed container with controlled humidity is essential. Protection from light is recommended, and it should be kept away from incompatible materials. Proper labeling and storage in a well-ventilated area are also critical for safety.
