Metabolite Identification
Common NameAcetohydroxamic Acid
DescriptionAcetohydroxamic Acid, also known as acethydroxamsaeure or lithostat, belongs to the class of organic compounds known as acetohydroxamic acids. These are organic compounds that contain a hydroxamic acid group carrying a methyl group attached to its carbon center. Acetohydroxamic Acid is a drug which is used, in addition to antibiotics or medical procedures, to treat chronic urea-splitting urinary infections. Acetohydroxamic Acid is an extremely weak basic (essentially neutral) compound (based on its pKa).
