2-(2-Oxo-1-pyrrolidinyl)butanamide(CAS: 33996-58-6)

2-(2-Oxo-1-pyrrolidinyl)butanamide is a white crystalline solid with a molecular weight of approximately 220.35 g/mol. It is sparingly soluble in water but soluble in organic solvents such as ethanol and acetone. The compound exhibits good stability under normal storage conditions but is susceptible to hydrolysis in the presence of moisture. It is slightly basic with a pKa of around 7.5.

2-(2-Oxo-1-pyrrolidinyl)butanamide is typically synthesized via the condensation of butyramide with 2-pyrrolidone in the presence of a base such as triethylamine. The reaction is carried out in an aprotic solvent like dichloromethane, and the yield is generally high, around 85-90%. This method provides good control over the selectivity and quality of the product.

2-(2-Oxo-1-pyrrolidinyl)butanamide is used in the pharmaceutical industry as a precursor for the synthesis of certain biologically active compounds. It is also utilized in the production of polymers and as a reagent in chemical sensing applications. Additionally, it finds use in the semiconductor industry for specific chemical processes.

When handling 2-(2-Oxo-1-pyrrolidinyl)butanamide, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be performed in a well-ventilated area, preferably in a fume hood, to minimize inhalation risks. If a spill occurs, it should be cleaned up immediately using absorbent material and disposed of according to local regulations. Refer to the Safety Data Sheet (SDS) for detailed information on handling and storage.
