 | Hazard Information | Back Directory |  | [Description] 
 Homovanillic acid (HVA) is a dopamine metabolite.1 It is formed via deamination of dopamine by monoamine oxidase (MAO) to produce 3,4-dihydroxyphenylacetic acid (DOPAC; Item No. 24912) followed by DOPAC metabolism by catechol-O-methyltransferase (COMT). HVA undergoes hydrogen peroxide-dependent oxidation in the presence of horseradish peroxidase to form a fluorescent dimer that displays excitation/emission maxima of 312/420 nm, respectively.2 It has been used to quantify hydrogen peroxide production in macrophages and neutrophils.

 white to beige crystalline powder
 |  | [Uses] 
 A neuroendocrine tumor marker.  Dihydroxyphenylacetic Acid (DOPAC) metabolite.
 |  | [Uses] 
 Fluorimetric reagent and major catecholamine metaboliteHomovanillic acid is used as a reagent in the determination of oxidative enzymes. It is associated with dopamine levels in the brain. Its presence supports a diagnosis of neuroblastoma and malignant pheochromocytoma.
 |  | [Definition] 
 ChEBI: A monocarboxylic acid that is the 3-O-methyl ether of (3,4-dihydroxyphenyl)acetic acid. It is a catecholamine metabolite.
 |  | [Biological Activity] 
 Fluorimetric  reagent  and  major  catecholamine  metabolite.  Used  for  fluorimetric  determination  of  oxidative  enzymes  including  glucose  oxidase.
