white to light beige crystalline powder or | [Uses]
4''-Hydroxy-3''-methylacetophenone is used in the synthesis of 3-De(hydroxymethyl)-3-methyl Salmeterol (D230650), which is an impurity of β2-Adrenergic agonist Salmeterol (S090100). | [Definition]
ChEBI: 4-hydroxy-3-methylacetophenone is a monohydroxyacetophenone that is acetophenone carrying methyl and hydroxy groups at positions 3 and 4, respectively. It has a role as a volatile oil component and an insect attractant. It is a monohydroxyacetophenone, a member of phenols and a hydroxytoluene. It is functionally related to an acetophenone. | [Preparation]
Preparation by dealkylation of 4-hydroxy-5-methyl-2-iso-propylacetophenone with aluminium chloride in chloro-benzene at 50° (53%). | [Synthesis Reference(s)]
