  Urine is often analyzed for the neurotoxic metabolite 2,5-hexanedione to evaluate n-hexane exposure. The major metabolites of n-hexane present in urine are 2,5-hexanedione and 4,5-dihydroxy-2-hexanone. Acid treatment (a routine step in chemical analysis of urine) converts 4,5-dihydroxy-2-hexanone to 2,5­ hexanedione (Fedtke and Bolt 1986a, 1986b).
