| Common Name | 3-Methoxytyramine |
|---|
| Description | 3-Methoxytyramine, also known as 4-(2-amino-Ethyl)-2-methoxy-phenol or 3-O-Methyldopamine, is classified as a member of the Methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. 3-Methoxytyramine is considered to be slightly soluble (in water) and acidic. 3-Methoxytyramine can be found primarily in human brain and most tissues tissues; and in blood, cerebrospinal fluid (csf) or urine. Within a cell, 3-methoxytyramine is primarily located in the cytoplasm |
