Common Name | 4-Methoxyphenylacetic acid |
---|
Description | 4-Methoxyphenylacetic acid is a monocarboxylic acid that is phenylacetic acid carrying a 4-methoxy substituent. It is used as an intermediate for pharmaceuticals and other organic synthesis. It has been found to inhibit the germination of cress and lettuce seeds. It has a role as a plant metabolite, a plant growth retardant and an Aspergillus metabolite. It is a monocarboxylic acid and a monomethoxybenzene. 4-Methoxyphenylacetic acid, also known as 4-methoxybenzeneacetate or 2-(p-anisyl)acetic acid, belongs to the class of organic compounds known as anisoles. These are organic compounds containing a methoxybenzene or a derivative thereof. 4-Methoxyphenylacetic acid is a 4-O-Methylated catecholamine metabolite found in normal human urine, cerebrospinal fluid and brain tissue. |
