What is 3-Methoxyphenylacetic acid?
Chemical properties
Off-White Solid
The Uses of 3-Methoxyphenylacetic acid
A fluorimetric method for the estimation of 4-hydroxy-3-methoxyphenylacetic acid (homovanillic acid) has been developed and applied to normal brain tissue. The presence of homovanillic acid in the caudate nucleus of normal animals of several species has been demonstrated.
Definition
ChEBI: 3-Methoxyphenylacetic acid is a monocarboxylic acid.
Purification Methods
Crystallise the acid from H2O, or aqueous EtOH. The S-benzylisothiuronium salt has m 160-161o (from EtOH). [Beilstein 10 I 82, 10 III 428, 10 IV 541.]
