Teratogenesis studies were performed in rats and rabbits given N-cyclohexyl-2-pyrrolidone, an aprotic solvent used in chemical processing. Dosages of 0, 15, 50, 150, or 500 mg N-cyclohexyl-2-pyrrolidone/kg body wt/day were administered by gavage to groups of 25 pregnant Sprague-Dawley rats

The compound N-cyclohexyl-2-pyrrolidone contains a substantial apolar region as well as a peptide bond-like moiety. This solvent, therefore, provides a useful model for protein interiors. Under certain conditions of temperature and salt concentration, cyclohexylpyrrolidone forms a two-phase system with water.

A new method for enhancement of ninhydrin or 1,8-diazafluoren-9-one (DFO)-treated latent fingerprints on thermal paper will be described. Most thermosensitive surfaces of thermal paper become dark when treated with DFO or ninhydrin petroleum ether (NPB) solution. This effect minimizes contrast
