Metabolite Identification
Common NameHeptyl 4-hydroxybenzoate
DescriptionHeptyl 4-hydroxybenzoate, also known as heptylparaben or nipaheptyl, belongs to the class of organic compounds known as p-hydroxybenzoic acid alkyl esters. These are aromatic compounds containing a benzoic acid, which is esterified with an alkyl group and para-substituted with a hydroxyl group. Heptyl 4-hydroxybenzoate is used as a food additive ("EAFUS: Everything Added to Food in the United States. "). Heptyl 4-hydroxybenzoate is a potentially toxic compound. No indication of carcinogenicity to humans (not listed by IARC). These are compounds containing an hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxylic acid. It is used as a food additive .
