Structure of the 2-Pyrrolidinone Monohydrate
Zeitschrift für Naturforschung B, 1999The X-ray crystal structure of the 1:1 adduct shows a complicated network of water and 2-pyrrolidinone molecules where the carbonyl oxygen atom of 2-pyrrolidinone forms hydrogen bonds with protons of two separate water molecules and the NH proton of the 2- pyrrolidinone molecule interacts with the oxygen atom of a third water molecule.

Disposition of N-Vinyl-2-Pyrrolidinone in the Rat
Drug and Chemical Toxicology, 1984The disposition of N-[14C-vinyl]-2-pyrrolidinone was studied in male Sprague-Dawley rats following a single iv injection. Plasma levels of the intact compound dropped rapidly within the first 6 hours after dosing with a half life of 1.90 hours. Urinary excretion by 12 hours represented 74.9% of a 5 microCi dose while 18.7% was excreted into the bile by

Journal of Physical Organic Chemistry, 1989
Abstract1H, 13C, 15N and 17O NMR chemical shifts, 1JNH and 1JCH coupling constants and line widths (Δν1/2) of the 14N and 17O resonance lines were determined for 2‐pyrrolidinone neat and for several 2‐pyrrolidinone–solvent systems. The 17O NMR chemical shift of 2‐pyrrolidinone was clearly most sensitive to the solvent effects, but changes with the ...
