title: Formation of methylurea from methylamine and carbamyl phosphate: a possible environmental hazard.
abstract: Methylurea, a precursor of carcinogenic nitroso compound, was formed by incubating methylamine and carbamyl phosphate in neutral buffer. The formation was checked on a radiochromatogram, as well as by color reaction. The presence of methylamine and carbamyl phosphate in preserved, fermented foods provided a suitable condition for the formation of methylurea.
