Metabolite Identification
Common NameTromethamine
DescriptionTromethamine, also known as trometamol or tham, 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. Tromethamine is a drug which is used for the prevention and correction of metabolic acidosis. Tromethamine exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). Tromethamine is also a parent compound for other transformation products, including but not limited to, bis-tris, bis-tris propane, and N-tris(hydroxymethyl)methylglycine.
