Talk:Vanillyl mandelic acid

From Wikipedia, the free encyclopedia

[edit] Chemical formula

The chemical formula in the box on the right looks wrong. I don't think there should be a nitrogen there. Also, I don't see any difference between this name and the name for homovanillic acid despite the extra OH group. 194.176.105.40 15:33, 29 April 2007 (UTC)

Chemical formula and molecular weight fixed, thank you. The IUPAC name is in fact different—there's an extra "hydroxy" here:
  • VMA: 2-hydroxy-2-(4-hydroxy-3-methoxy-phenyl)acetic acid
  • HVA: 2-(4-hydroxy-3-methoxy-phenyl)acetic acid
Thanks again for pointing this out. Fvasconcellos (t·c) 16:04, 29 April 2007 (UTC)
