Metanephrine-d3 is intended for use as an internal standard for the quantification of metanephrine by GC- or LC-MS. Metanephrine is an inactive metabolite of epinephrine .1 It is formed from epinephrine by catechol-O-methyl transferase (COMT).2 Urinary and plasma levels of metanephrine are increased in patients with pheochromocytoma, an adrenal medullary neuroendocrine tumor.3,4
