Metabolite Identification
Common Name(4-Ethoxyphenyl)urea
Description(4-Ethoxyphenyl)urea, also known as dulcin? or p-ureidophenetole, belongs to the class of organic compounds known as n-phenylureas. N-phenylureas are compounds containing a N-phenylurea moiety, which is structurally characterized by a phenyl group linked to one nitrogen atom of a urea group. Based on a literature review very few articles have been published on (4-Ethoxyphenyl)urea.
