| Description | 2-Hydroxy-N-(2-hydroxyphenyl)acetamide, also known as HHPAA, belongs to the class of organic compounds known as anilides. These are organic heterocyclic compounds derived from oxoacids RkE(=O)l(OH)m (l not 0) by replacing an OH group by the NHPh group or derivative formed by ring substitution. Based on a literature review very few articles have been published on 2-Hydroxy-N-(2-hydroxyphenyl)acetamide. |
