Metabolite Identification
Common NameDiethanolamine
DescriptionDiethanolamine, also known as H2DEA or diolamine, belongs to the class of organic compounds known as 1,2-aminoalcohols. These are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. Diethanolamine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. Diethanolamine exists in all living organisms, ranging from bacteria to humans. Diethanolamine is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound.
