<p>DL-4-Hydroxy-3-methoxymandelic acid is a metabolite of the catecholamines, norepinephrine and epinephrine. It is found in the blood, urine and cerebrospinal fluid of humans. DL-4-Hydroxy-3-methoxymandelic acid is derived from the amino acid tyrosine. When the body's production of catecholamines exceeds its ability to break them down, these molecules accumulate and are excreted in urine as DL-4-hydroxy-3-methoxymandelic acid or as other metabolites. The concentration of DL-4-hydroxy 3 methoxymandelic acid in urine may be used to diagnose pheochromocytoma or neuroblastoma.</p>
