Common Name | p-Hydroxymandelic acid |
---|
Description | P-Hydroxymandelic acid, also known as 4-hydroxymandelate or 4-hydroxyphenylglycolate, belongs to the class of organic compounds known as 1-hydroxy-2-unsubstituted benzenoids. These are phenols that are unsubstituted at the 2-position. p-Hydroxymandelic acid was first documented in 1979 (PMID: 487594). P-Hydroxymandelic acid is an extremely weak basic (essentially neutral) compound (based on its pKa) (PMID: 3706738) (PMID: 3091293). |
